Does anyone know if you can have different functions or activities in your app on the phone vs pad?
For some games/educational, some activities/functions work better on a larger screen. Does apple allow some activities to be limited on the phone side for a universal app?
I would like to know if apple allows iPhone and iPad not to match exactly in terms of functionality in a universal app.
thanks

Maybe you want just to write different code for iPhone / iPad? If so, you can refer this answer and then just use different implementations for functions

The apps provide the same functionality, but have different code bases.
Is this possible?
I'm not entirely sure what you mean by "bundle" in this instance. PhoneGap provides the ability to deploy your app to numerous platforms (iOS, Android, Windows Phone) by writing in just HTML5, CSS, and Javascript. Your question states that you have a functioning HTML5 version of the app written for the PhoneGap platform. If this is the case, what is the need for the Objective-C iPhone app? Simply maintaining the HTML5 app should be sufficient to deploy to both iPad and iPhone. PhoneGap currently supports iOS, iPad, and retina displays.
From the PhoneGap documentation, you can specify differences in your interface using config.xml.
You can mix phonegap and native code fairly easily - just have the startup code check the platform type and display either the native view or the phonegap webview.
However, whatever you do at this point will result in some inconvenience to users - the only way to share in app purchases across devices is to have a single universal app. If you want to keep existing purchases, you have to add an ipad view to the existing iphone app, but that will not show up as an update for anyone who has the existing iPad app.
There are other possibilities such as setting up a server to track purchases in both apps, but that gets a lot more complicated than standard in app purchase and only works if your app includes a login system.
I'm aiming to do an app like Badoo:
http://itunes.apple.com/us/app/meet-new-people-chat-socialize/id351331194?mt=8
Basically it involves chatting with people and GPS geo-location.
Question is - I have two options:
A. Have this developed in native XCode for iOS
OR
B. Have this developed in HTML5 + PhoneGap
Assuming either route is with an experienced developer, how much time does B save over route A in terms of getting a viable product out?
Performance， speed, and UI are all important for this, so obviously native is ideal... but how much time would PhoneGap save in getting it out?
Thanks so much！
Have this developed in PhoneGap, as you can target multiple platforms. And also phonegap also supports geo location functionality. so its a win win with phonegap.
if you are going to target ONE platform, do the Xcode route. if you are going to target android and ios together, then please Phonegap.
I'm a fan of native development even if you are deploying to multiple platforms.
However, the main point is if you have skills in html/css/javascript and potentially want to support multiple platforms then by all means go with PhoneGap.
If you have skills in iOS development then go native and reconsider what to do if you want to support other platforms later.
IMO, once you've developed an application in one language, then the amount of effort required to do another version in Android, PhoneGap, or whatever is greatly reduced. If you know the target platform well it is painting by numbers.
If you are building for iPhone/iPad (JUST IOS), then xcode will be your best friend and it will be much faster to develop in xcode in that case, as documentation and sites like this one (stack over flow) have many code snippets around and it will make your life easier. And not to mention that storyboards are also excellent in making your User interface. If you take the xcode route, it will still take you roughly the same amount of time as phonegap.
HOWEVER, if you want to make the SAME app for iphone and android, then phonegap will save you 50% project time, and this only applies when you are talking about one app for both android and iphone
Just out of curiosity, where do your skills lie in? ios or html/css?
Where could someone get the code or guidelines to create a universal pedometer app for various phones?
or would you have to create a different app for each phone?
or could you just create an app for android & iphone?
How would a coder go about doing the task? where to look for help?
Titanium Mobile is a cross-platform dev environment that lets you write apps in javascript that are then compiled into native apps for iPhone/iPad and Android. I haven't used it myself, but I've heard that it does not completely suck. I do not know whether it supports the accelerometers in these devices (which would be necessary for a pedometer app), but it probably does.
However, since you'd have to learn a bunch of new stuff just to use Titanium, it might make more sense to just pick a platform and spend your time learning to program it natively (Android has more marketshare now - maybe - so I'd recommend just learning that; Android is much easier to work with than iPhone).
Titanium Mobile does support Accelerometer.
For iPhone, there is an offical library in the framework that will detect steps, but it will only work from iOS7.
Look here: /System/Library/Frameworks/CoreMotion.framework
Please be aware there are restrictions for what kind of Apps can run in the background on an iPhone.
Is it possible to develop an iphone app that tracks use of other apps. Basically is it possible to track how long a person used each iphone app on their phone?
Provided that you wrote the other apps it is. Basically it would be an interface to something like http://www.flurry.com/. Otherwise no.
I searched first, so apologies if it's already been asked.
I have a couple iPhone apps that I want to run as native iPad apps rather than in "mini-mode" for lack of a better term.
What do I need to change to build my app for the iPad and is it easy to target both platforms from the same project?
Yes, it's easy to target both platforms. If you login to ADC and read the iPad Programming Guide, it'll provide the basics for iPad specific development. I can't legally speak of the "how."
Um. If you follow their directions, build two targets, share your source within the same project... then you'll be set. It's the same SDK, just different Nibs & main(), from what I can tell.
I know this isn't very helpful on a technical level, but...
The new iPad SDK site specifically mentions the term "Universal Applications" with the following:
Developers can now start planning for
universal applications, allowing them
to take full advantage of the
technologies found on iPad, iPhone,
and iPod touch with a single binary.
I know this doesn't explain ''how'' to take advantage of this idea, but I'm not quite willing to drop 100 dollars to learn more just yet.
But this does resolve your core goal, which is designing apps that can work nativly on both devices. With the a universal binary, you wouldn't need to worry about covering idiosyncrasies for two versions of one project unless you wanted device-specific features.
