Several years ago I released an app (a free game) for iOS, which was largely unsucessful, settling to around an average of 5 downloads a month (terrible, I know). However, I recently happend to notice a huge (relatively) spike in downloads, up to around 300 downloads over the last 10 days.
Something seems strange about this latest batch of downloads however, for one thing they are all from China (My app is only localized for English, and never marketed outside the U.S.), and the "Active devices (opt-in only)" statistic shows 3 devices used over that same time period.
Even stranger, the "Product Page Views" statistic shows only 6 views over this same period that had 300 downloads?!
Is something nefarious going on, or might there be a benign explanation for this huge spike in downloads?
If anyone is curious, or if it helps find the cause, the app is Acorn Mayhem, as found here. (Note: this is not intended as self promotion, and if including the link violates stack overflow rules, feel free to edit it out)
in response to being put on hold:
This question appears to have been put on hold as "off topic", I don't belive it should be, it does involve tools used directly and exclusively for programming (iTunes connect, which is only used by programmers) It would not be seen by the people who actually use it if it was on superuser, and I think the number of other people who have experienced the same problem and replied in a short time shows that it is on topic and helpful to a large portion of the programming community.
There is a thread on Apple forums about the issue https://forums.developer.apple.com/thread/84146
I reported this to Apple yesterday through iTunesConnect and received a call back today (my spike started 8/16 and is just starting to trail off now). They are investigating this; the call lasted over 10 minutes. They promised to keep me in the loop so I will report back when I hear something.
same here too. a game I released a year ago had very few downloads. Over the last two months I have seen a slight increase in downloads, 1 or 2, maybe up to 5 per day, all from China. All of a sudden in the last week I have seen 50, 80, and yesterday it peaked at 123 downloads.
I should also mention, this is a free game, with AdMob adverts.
Either the people who download the game aren't actually playing it at all (not one single ad show in China) or AdMob just doesn't work in China ???
either way - I've had about 500 downloads in the last week compared to ~300 in the entire previous year.
there is an IAP to upgrade the game and remove ads, needless to say, not one single user has paid.
a very strange situation. I wish I knew what was driving the Chinese downloads but I can't find anything pointing to my game ?! Also iTunes Connect seems to say they are coming from store browsing ?!
curiouser and curiouser ...
Similar story here:
I have 2 apps, that I made about 2 years ago basically for fun. They get about 20-35 downloads per day. Since 17 Aug, they receive about 120-150 per day, all the extra downloads from China. These numbers don't have any effect on my admob performance, and no significant changes on firebase. I call them ghost-downloads.
I switched one of the apps from free to paid. The downloads for that app went down to zero (as I expected)
If you want to have an accurate real user traffic stats, check the "Daily Active Users" & "Daily Active Devices" from itunes connect as reference.
From my own stats, I can see there are extra ~100 download spike daily from Chinese market, but the DAU stays the same, which means these downloads were not initiated by users, might be a 3rd party app crawler automated the crawling for apps using simulators or automation iOS devices. So don't worry about it, the trend should go away in a while.
If you are curious which 3rd party app crawlers are downloading your apps, google "[your app name] + 应用", you should find tons of them. Websites like these crawl lots of app data and run SEO to attract traffic, and benefits from online advertisements (adsense, etc.)
I have the same phenomenon across free apps in the App store. It results in approximately 1000 downloads from China per day, spread pretty evenly across about 15 apps. Each app download is around 100-200MB so that implies a reasonable burden on the App store servers if it is happening with other apps also. I contacted Apple and they did not seem to ask anything but questions that clearly indicated a complete lack of interest in understanding the issue. They suggested that the problem was not a problem but a volume download program. They then asked to see screenshots from affected users.
The exact same thing happened to me (hundreds of extra downloads per day from China only) within the past week. It's not just one app but every one I have created so far. At first I thought it was an iTunes Connect bug but maybe my apps were just featured somewhere public? There are over a Billion people there after all. ;)
I would like to confirm this, and share some data as well. Take a look. The deviation in traffic started around mid of July, and all of my apps have been downloaded roughly in the same amount. Few days ago I noticed that downloads returned to their normal level. All of abnormal purchases took place from China. Maybe this will shed some light on the source, but I doubt that this traffic generated by real people.
At first I thought this was great news, a lot of downloads, but then my cynical side popped in. Perhaps they are downloading the IPAs unzipping them and looking at the source code. They would only have the front end, but that's half the solution. Here is an article about pirated apps
https://www.cultofmac.com/224075/china-has-its-own-app-store-that-lets-users-install-pirated-ios-apps-without-jailbreaking/
You want to look for ways to obfuscate your code.
Updates:
By the end of September my abnormal Chinese ghost-downloads have disappeared. Everything is back to normal.
On the 8th of September I experienced something much more extreme an unexpected: Approximately 6000 "downloads" from Sweden. It happened only once.

I know the review process is unpredictable at best. To avoid a discussion of opinions, I'm looking for answers from people who have submitted apps without localizations, then submitted the same app later with the only changes being the addition of localization in several languages.
If the review process is significantly longer than the original app, then the answer may be yes.
I'm curious if they need to send the app to different countries for review, as some countries will block certain types if information (China, for example).
Of course if you can post information other than this which is still relevant it would be appreciated.
If you are submitting the app during the christmas holiday season rush, review times may be more. The average per day app submission in this time is lot higher due to Apple shutdown during holidays, and developers trying to get their app just in time before shutdown.
That said, here's my observation for non-holiday seasons submission. We have an app that has been localized for 24 locales, including China. I never experienced any specific pattern in changes in review times before localization was put (was english only at one time, later all the localizations were added) vs after localizations were added. I had one time an update that went live within 48 hours of submission with around 19 localizations (including chinese, finnish, russian etc in it) in it. On the other hand, once a Finnish only app that I submitted took almost 2 weeks. Most of my apps are utility or education.
I think its more to do with type of app + rating (if its got some controversial material in it) + when you submit it (christmas holiday season or not).
I am building an app for a client that will have 30 days of content for free, thereafter you are required to buy a subscription via in app store purchases.
However, I have read that you will get rejected if you have trials.
Don’t set time limits on any of the functionality of your app, either
for run times or life times. Applications that only run for a set
number of minutes per session, or that expire altogether after some
period of time, don’t recruit customers so much as leave a bad taste
in their mouths.
Finally, they also say "your app will be returned to you by the App Review Team for modification if it is found to have time limits".
This seems odd because I know the Guardian and all major newspaper apps have limited functionality.
The Guardian app is free but you get limited functionality?
The Daily app is free, but you have to pay for daily subscriptions
and has limited functionality for the period of your subscription.
The Times app is free, but is a free trial (of sorts) (plenty of
complaints about it)
There are other examples which seem to differ from Apple's policies.
Lets say you have an app that is free, but then you have to pay for subscriptions to gain access; however according to the rules this is considered limited functionality -- yet there are lots of newspaper apps that do exactly that.
I'm confused.
Can someone clarify the situation? Can apps have trials?
Thanks
It is difficult to clarify the situation because unfortunately the guidelines are not necessarily set in stone. They can and do vary on an app and publisher basis.
In the case of The Times and The Daily, both apps are produced by News Corp. It is perhaps safe to say that News Corp has a good deal more influence with Apple than a one-man development shop producing an iPhone game. Apple would be loath to admit it, but there are clear cases of popular apps on the store that don't conform to the guidelines, where they have tacitly made an exception.
So what I would say to you is this: be sensible. Don't have an app that quits automatically when your trial runs out. Think about what would be acceptable to users. It's very much a case of nothing ventured, nothing gained. Take a risk, submit your app with your limited trial, and see what happens.
With the Guardian app, we had to deliver an app where you always got at least some fresh content if you were using the free version. Subscribing opens up more content to the user.
I think, you are mixing up "content" and "functionality".
You can deliver content items (i.e. an magazine issue) for free or user has to pay for it — so the first n issues, or all issues in a certain timeframe, can be free, while the others need to be paid. But if an user purchased an content item before, you have to re-deliver it for free.
You can sell functionalities (i.e a search in the magazine's archive) as-well. But you cannot give it to the user for free for a certain time and them make him pay.
So the general rule is: What ever the user got from you — you cannot take it back from them and make them purchase it again.
There are plenty of free apps which provide limited functionality. They don't provide time limits though (or at least they shouldn't). I'm guessing it won't be as clear cut as accept or reject for Apple, because I did encounter an app which closes itself after 10 minutes, opening a web page to purchase it (closing an app is also against the Apple Human Interface Guidelines, as an app should never terminate itself).
The guidelines mention this is only allowed for specific types of content:
11.9 Apps containing content or services that expire after a limited time will be rejected, except for specific approved content (e.g. films, television programs, music, books)
11.15 Apps may only use auto-renewing subscriptions for periodicals (newspapers, magazines), business Apps (enterprise, productivity, professional creative, cloud storage), and media Apps (video, audio, voice), or the App will be rejected
what are the advantages and disadvantages in using Flurry or Localytics?
I can't answer about iOS, but the Android libraries for Flurry had a very half-baked feel to them when I tried them out about 3 months ago. There's a lot less power in their stats reporting and drilling down through the data can be like pulling teeth.
Additionally, I was getting wildly inaccurate session counts in a small closed beta test of my app (1000 sessions reported in a few minutes from one device). When I contacted Flurry support, it took them nearly a week to get back to me and then all I got was a fairly useless stock response. That alone knocked them straight off my list of potential analytics providers.
I've used Localytics on Android for hundreds of thousands of total installs at this point and am quite happy. Android gets treated as a first-class citizen (rather than feeling like a bolt-on on Flurry or even Google Analytics), and they have a pretty nice looking UI with a lot of good drilldown controls.
Both services are free and both services provide the same basic functionality of providing app analytics (e.g. number of users, type of devices, how the users are interacting with the app, etc.).
I have used both services for Android, although I am currently using Localytics because the Localytics library is open source. The Flurry library is closed source. Open source has the advantage that you can modify the library, as well as see exactly what the library is collecting.
Using flurry in your app you can trace your app, Suppose you want to track that this button pressed how many times ,You can use flurry it shows that in this location this app is used and that button is pressed that number of times.
DISADVantage:- Flurry is very slow it gives you results in 14-15 hours.
ADVANTAGE:- it is free
OTHER :- in place of flurry you can use google analytics(free) and omniture(Paid but give result faster)
you have to register yourself in flurry.com
Both of them store the data in public area. Although the data is so-called privacy, but it's not on your own server.
Flurry is free but provides much less detailed information, and flurry also only accepts up to 10 parameters per event. Localytics makes it easy to sort your data in many ways. For example I can look at all my users for the past week, now I can view users per day, or per hour. Then I can split the data to show me which users that played in the last week started playing the game for the first time, and then I can view that chart scaled to 100%. I could then add a filter so that I'm only looking at data from the users that started on a specific date, or specific week, or even multiple specific dates/weeks/etc. There are only a few things that I'd like from the localytics website that they don't provide, like retention data for days 8-13, or 15-27, or past 28 days, but those things can all be done through SQL queries.
Basically, flurry is free, but basic compared to what you get from localytics. Localytics I believe is free up until 10k MAU (monthly active users). Using localytics over flurry has made a huge difference on the product I'm on, we have been able to make much better decisions based on data.
We are currently in the process of evaluating a couple of iPhone development shops and we're putting together a list of questions/topics that we'll be asking them about when we meet.
To make sure that we have the most relevant areas covered, what would you ask when evaluating an iPhone developer or development shop?
Our main areas are: applications shipped and quality thereof, planning process, development methods, testing frameworks, how they manage the ad-hoc beta testing, and the on-going process of bug fixes and re-submission to the app store.
I have coded and shipped an app, so I have enough experience with it to ask pertinent questions. What kind of specific development questions would you guys want to cover before feeling satisfied with someone's abilities?
Thanks!
If you ask for things like code, requirements document, etc, they'll probably send you the best of what they have and that might not be the status quo. At the same time it doesn't hurt to take a look over such things and see how they handle the request.
Since 90% of the iphone shops have a life of about 2 years (most people have jumped on the iphone bandwagon in the last few years) I wouldn't hold that against them but I'd make sure they have a development background and didn't start their development career on the iphone in the last 2 years [1]. If I was outsourcing any type of work (iphone, web, desktop), I'd want to work with a group that has been through a handful of the ups & down's of developing, delivering and supporting software, plus has the client skills to match.
Meaning they can communicate, know how to manage and know how to run the development side as well. I'd like it if they at least had some development history/experience in C or C++.
Also, do they have artists and such in house or do they outsource the asset creation? (Maybe its not needed for your app besides an icon & splash screen).
What software do they use for bug tracking? How do they manage their development cycles? Do they use a methodology? (waterfall, agile, etc)
Do they offer support? How much is it? Contract? Per instance?
Do you get the source? You should, you paid for it.
Speaking to them is very important, and your gut will tell you much about them. If you can drop by and checkout their shop that's cool too. But don't hold a small shop against them - it should just mean better rates for you due to lower overhead.
If they've done consulting work, and have shipped app's that's a benefit. Specifically question them about ad-hoc distro.
And importantly, have they worked with the technologies you need (say openGL for a game, or consuming web services for a network related app)? Again, not necessarily a strike against them if their smart and eager, but you'll be appropriately aware of their current abilities.
Good luck!
Also, if they're willing to work on equity alone, I'd be worried. Developers are making good money on the iphone and I see no reason to take equity only. I consult on the iphone, and I won't accept equity deals. Cash is king.
[1] What I mean is that, I would expect them to have developed on other platforms (web, desktop, other mobiles) NOT just the iphone. So if they started programming in the last year, on the iphone alone, that's probably not a firm I want to work with. If they had developed desktop applications for the last 5 years and then came to the iphone world in the last year or so, that's cool. I just want to work with people that have gone through the first couple years of development - those are great great great learning years (but don't want them doing it on my dime).
Ask them for a portfolio. Then buy those apps that they have worked on and see if you like them.
Ask them how long they've been developing iPhone apps for the AppStore.
If it's longer than 18 months, find someone else.
I would say process and experience are most important. Items like:
Describe your process
How much involvement can I have- access to tools, developers, etc.
Tell me about projects you've done that overlap or featuresets that overlap mine.
Do you outsource? Or who, specifically will be working on my app?
How do you handle maintenance?
How do you handle payment?
Items like this are a good start to a dialog between the two of you. Theres really a lot to consider when developing an app. I think coming into the conversation really well prepared on your product will give you an understanding of the right questions to ask.
Closed. This question is off-topic. It is not currently accepting answers.
Closed 11 years ago.
Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
How much can a developer charge for an iPhone app like Twitterrific?
I want to know this because I need such an application with the same functionality for a new community website. I can do Ruby but have no experience with Objective-C. So it would be interesting for me if I should start reading books about iPhone programming or outsource the work to a iPhone programmer.
I'm one of the developers for Twitterrific and to be honest, I can't tell you how many hours have gone into the product. I can tell you everyone who upvoted the estimate of 160 hours for development and 40 hours for design is fricken' high. (I'd use another phrase, but this is my first post on Stack Overflow, so I'm being good.)
Twitterrific has had 4 major releases beginning with the iOS 1.0 (Jailbreak.) That's a lot of code, much of which is in the bit bucket (we refactor a lot with each major release.)
One thing that would be interesting to look at is the amount of time that we had to work on the iPad version. Apple set a product release date that gave us 60 days to do the development. (That was later extended by a week.)
We started the iPad development from scratch, but a lot of our underlying code (mostly models) was re-used. The development was done by two experienced iOS developers. One of them has even written a book: http://appdevmanual.com :-)
With such a short schedule, we worked some pretty long hours. Let's be conservative and say it's 10 hours per day for 6 days a week. That 60 hours for 9 weeks gives us 540 hours. With two developers, that's pretty close to 1,100 hours. Our rate for clients is $150 per hour giving $165,000 just for new code. Remember also that we were reusing a bunch existing code: I'm going to lowball the value of that code at $35,000 giving a total development cost of $200,000.
Anyone who's done serious iPhone development can tell you there's a lot of design work involved with any project. We had two designers working on that aspect of the product. They worked their asses off dealing with completely new interaction mechanics. Don't forget they didn't have any hardware to touch, either (LOTS of printouts!) Combined they spent at least 25 hours per week on the project. So 225 hours at $150/hr is about $34,000.
There are also other costs that many developer neglect to take into account: project management, testing, equipment. Again, if we lowball that figure at $16,000 we're at $250,000. This number falls in line with Jonathan Wight's (#schwa) $50-150K estimate with the 22 day Obama app.
Take another hit, dude.
Now if you want to build backend services for your app, that number's going to go up even more. Everyone seems surprised that Instagram chewed through $500K in venture funding to build a new frontend and backend. I'm not.
The Barack Obama app took 22 days to develop from first code to release. Three developers (although not all of them were full time). 10 people total. Figure 500-1000 man hours. Contracting rates are $100-150/hr. Figure $50000-$150000. Compare your app to Obama.app and scale accordingly.
There are ways of paying less to get an application, developed than paying the going rate, but very often you get what you pay for - inexperienced developers who leave you with a mess of spaghetti code that's impossible to maintain, or experienced developers with whom you have to communicate across a cultural and language gap.
Developing an app like Twitterific is not easy. It's an extraordinarily polished app with a lot of attention to detail that most people - indeed many developers - would fail to notice or realize the effort behind. You may be able to get a Twitter iPhone client written for $3500 or $5000 by going offshore or by being willing to "work with inexperienced developers", but you're not going to get Twitterific for that, and it's doubtful you'd get even a halfway decent application for that amount.
And you likely will end up spending a lot of time managing the process, going back and forth on requirements, and fighting to get what you really want instead of what they want to give you.
There's also a risk with "cut-rate" development, whether it's offshore or just using inexperienced developers - you may very well end up with something you can't use, or something that gets 1 star ratings because it crashes or behaves erratically. You might find the occasional underpriced gem of a developer, but they won't stay underpriced for long given the sheer demand in this market right now.
By virtue of my books and blog, people often reach out to me when they need help with their iPhone applications. I get, on average, 4 or 5 inquiries a month from people asking for help fixing applications they had developed either over-seas or by inexperienced developers here in the States. In most cases, I end up having to tell them they'd be better off throwing their code out and starting over with a developer who knows what they're doing rather than trying to fix the code they bought on the cheap. If they insist on trying to "fix" what they have, I decline the work.
I am a very good iPhone app developer, and I charge over $150 per hour for my services. I have a ton of experience building iPhone apps and their server side components. I have also been called in on several occasions to fix offshore developed apps. Here's my take.
Design costs money, good design costs lots of money. Expect several designer weeks of work per app screen. Offshore teams do not do design.
Server development and infrastructure is critical if the app is to succeed. A slow server response, or an overloaded server will hamper your app, and crimp sales and satisfaction. The server side of the equation will cost the most and take the most time to develop. Those who offshore their server development will find that quality and uptime are both terrible, in my experience.
App development if done right takes time too. A professional developer will ensure all HIG rules are followed, the app is properly structured and contains no known errors, it performs well, and it passes the app store validations. Offshore teams just cut code.
I'm just about to release a shopping app for a client. The design work was done by 2 client in-house designers over 2 weeks, quick because they had all the image assets already. Think 2 people x 10 days x 8 hours = ~$24,000. The server side had to be modified to provide data for the iPhone app. We used their in-house team and in-house platform and in-house API, 2 developers, 4 weeks, or about $50,000 and that's because they already have a web shop and API. Cost them about $400,000 to get there (excluding platform). And I wrote the app side in 3 weeks, given that a lot of my code is duplicated from previous projects, another ~$25,000, the cheapest app I ever did.
Total spent: ~$100,000, and that's insanely cheap!
And they will give this away for free so clients will buy from their store from their iPhones.
For your app, Peter, if you have the servers and the APIs and the design, I'd guess at $30,000 to $60,000 depending on complexity. If you do not have the design, double it. If you do not have the APIs, double again...
I am an account exec at a web and mobile development company and hear this question everyday. Unfortunately, iPhone apps are not cheap. You can expect around $100 per hour if you are staying on US soil. I have seen some offshore Indian developers out there for as low as $20 per hour. It all depends on the number and complexity of the functions you wish the app to perform. Simple one function apps are normally around 4-5k. They are so expensive because you are paying a team of people a healthy hourly wage and any type of raw prototyping, development, and coding takes time. Apps can exceed 60-100k pretty easily. Southwest Airlines making an app with a full ecommerce platform that allows you to buy tickets over your phone is an example. All of that porting into their IT is a big job.
And offshoring the project is definitely not always a better option. If you do so you better know who you are dealing with. Do not get me wrong there folks over there who do a bad ass job for a way better deal, but they are not that easy to find. Those guys could fuck around for 5 months on a simple project that would take 6 weeks here, or just not complete it at all and hand it over half finished. I have seen this scenario many times where we finish the work. The project management becomes a challenge. It can be difficult to communicate exactly what you want the app to do.
River of News for the iPad took about 400 hours of development to get to version 1.0 and I don't know how many hours my designer spent (20-50?). At US labor rates that's at least $40,000. But that sort of tight development was only possible because it was a one man operation. There is an enormous amount of overhead added when you separate the person writing the code from the person deciding what the product is going to do.
If you are going to send it offshore you'd better know exactly what you want. With the language and time difference it's very hard to do iterative design where you are exploring what is possible.
Appsamuck iPhone tutorials is aiming for 31 days of tutorials ending in 31 small apps developed for the iPhone all the source code for which is available to download. They also provide a commercial service to build apps!
If you want to know if you can do the coding, well at least you can download the code and see if anything there is helpful for your needs. On the flip side you can also get a quote from them for developing the app for you, so you can try both sides of the coin, outsource and in-house. Of course it all depends on how much time you have too! It's certainly worth a look!
(OK, after my last disastrous attempt to try and post a useful piece of help, I went off hunting around!)
I am the developer for Coupious mobile coupons iPhone app and with the amount of time that I spent on that application (v1.0 - v1.5), it was probably a $15,000 - $20,000 investment. However, to be fair, I do admit that I was the only developer working on it and when I started the project, I had never seen or used Objective-C before. Despite that, three months later, it was released so the numbers are probably a little skewed because there was a fair amount of learning going on as well as coding.
However, iPhone competent developers run in the range of $80-$150 depending on their skill and time with the platform. I would say that for a simple application, an app would probably run 2K-5K, a medium complexity app would run 5K-15K and a fairly complex app running 15K-30K. Game applications could be even more.
The reason it is so high is that the skill is fairly specialized and not everyone is able to do it
I hate to admit how little I've done an iPhone app for, but I can tell you I won't be doing that again. The guy who said that "simple, one function apps can be done .. [by solo developers]... for $5K" is correct; however, that is still lowball, and presumes almost no project design, graphic design or network backend work.
The rates that were quoted above are what you would expect to pay US developers; however, I do know some people who have been able to get their apps built for as little as $4,000 by using offshore developers.
Here is a blog post from a group that did this: http://www.lolerapps.com/why-outsourcing-iphone-apps-was-a-no-brainer-for-us
Also, Carla White wrote a fantastic eBook about the process she used to outsource her app called "Inside Secrets to an iPhone App". She talks about how she got a great deal because she was willing to work with a team that was still learning iPhone app development.
So, there are alternatives to the higher price developers discussed above.
