Apple Touch Icon (Homescreen icon) for iPhone 7? - iphone

I would like to provide a custum Homescreen Icon for iPhone devices. This is the code I have after my -Tag:
<link rel="apple-touch-icon" href="../img/apple-touch-icon-120.png" sizes="120x120" />
<link rel="apple-touch-icon" href="../img/apple-touch-icon-144.png" sizes="144x144" />
<link rel="apple-touch-icon" href="../img/apple-touch-icon-180.png" sizes="180x180" />
This is working fine on 6s but it not working on iPhone 7. What did I do wrong?

Apparently there are no differences between iPhone 6 and 7 regarding the Touch icon. And if there were, the iPhone 7 would probably support the legacy icons.
The error might be due to a caching issue of some kind. If you already visited the site with your iPhone 7 before the Touch icon was available, maybe your phone is simply too "lazy" to notice it immediately. It would be useful to retry with your iPhone 7, or to try with another iPhone 7.
Another useful check would be to run RFG's checker against your site. It can spot several issues, like broken links or ill-formed images. Full disclosure: I'm the author of this service.

Apple touch icon (iphone retina) not applied - something wrong?

I have 4 icons for my site:
iPhone
iPhone Retina
iPad
iPad Retina
They're all working perfectly apart from iPhone retina (144x144), which is just showing the usual low-rez iphone icon (57x57). Below is my code, please tell me what I'm doing wrong.. All paths/images/sizes are correct.
Thank you.
<link rel="apple-touch-icon-precomposed" href="app/img/touch-icon-iphone.png" />
<link rel="apple-touch-icon-precomposed" sizes="72x72" href="app/img/touch-icon-ipad.png" />
<link rel="apple-touch-icon-precomposed" sizes="114x114" href="app/img/touch-icon-iphone-retina.png" />
<link rel="apple-touch-icon-precomposed" sizes="144x144" href="app/img/touch-icon-ipad-retina.png" />
Did you rename 114x114 images picture name with #2x ? imageName#2x etc.
set iPhone retina Image Name touch-icon-iphone#2x.png . that is 144*144.

do we need separate icons for iPad and iPhone?

I am thinking of designing a a website which sort of looks like an app.So im in the process of designing the icons and creating the css for it. I was wondering if I have to do separate icons for iPhone and iPad bcos iPad will surely need bigger icons.Sorry if I posted the question in the wrong section.
Thank You
iOS Human Interface Guidelines - Web Clip Icons:
For iPhone and iPod touch, create
icons that measure:
57 x 57 pixels
114 x 114 pixels (high resolution)
For iPad, create an icon that measures:
72 x 72 pixels
Safari Web Content Guide - Specifying a Webpage Icon for Web Clip:
To specify multiple icons for
different device resolutions—for
example, support both iPhone and iPad
devices—add a sizes attribute to each
link element as follows:
<link rel="apple-touch-icon" href="touch-icon-iphone.png" />
<link rel="apple-touch-icon" sizes="72x72" href="touch-icon-ipad.png" />
<link rel="apple-touch-icon" sizes="114x114" href="touch-icon-iphone4.png" />
Since the screen resolution is different for both devices, maybe you'd want to route them to completely different pages based on the user-agent string.
That way, you can design the optimal UI for both devices.
Yes this can be best idea to use separate style sheet
you can use following code -
because difference in DPI you have to use hi DPI for ipad and iphone's icons
Refer the following link.
It contains an iPad like simulator in browser. It has all the images as like the iPad.
Since it is a web content, I hope that you will get some resources from here.

Splash Screen for iPhone and iPad on the same HTML/Javascript App

I am creating an application in HTML and javascript for iPhone and iPad.
I would like to have a splash screen for both devices since they must have different dimensions.
I know that there is a link tag "apple-touch-startup-image" that allows you to specify the link for the splash screen image.
What do I do if I want to specify 2 different links? I put 2 link tags with rel="apple-touch-startup-image" and 2 different URL?
Will the mobile device take the correct one if I respect the naming convention here?
What are the sizes used for the iOS application splash screen?
Thanks!
Just figured out how to do this, and it's similar to the apple-touch-icon setup.
Here's my example:
<link rel="apple-touch-startup-image" href="iPhonePortrait.png" />
<link rel="apple-touch-startup-image" sizes="768x1004" href="iPadPortait.png" />
Just set the "sizes" attribute to the specific width and height and mobile Safari should match it up correctly. You can see the various width/height values from the link you posted, too. Hope it works!
I don't believe this is possible on web apps. The naming convention in that question will not work, it is for native apps.

What size should apple-touch-icon.png be for iPad and iPhone?

Are Apple touch icons bigger than 60x60 supported, and if so, what dimensions should I use for the iPad and iPhone?

Use these sizes 57x57, 72x72, 114x114, 144x144 then do this in the head of your document:
<link rel="apple-touch-icon" href="apple-touch-icon-iphone.png" />
<link rel="apple-touch-icon" sizes="72x72" href="apple-touch-icon-ipad.png" />
<link rel="apple-touch-icon" sizes="114x114" href="apple-touch-icon-iphone4.png" />
   
This will look good on all apple devices. ;)
With the iPad (3rd generation) there are now four icon sizes 57x57, 72x72, 114x114, 144x144.
Because retina icons are exactly double the size of the standard icons we really only need to make 2 icons: 114 x 114 and 144 x 144. By setting the retina sized icon to the corresponding standard icon iOS will scale them accordingly.
<!-- Standard iPhone -->
<link rel="apple-touch-icon" sizes="57x57" href="touch-icon-iphone-114.png" />
<!-- Retina iPhone -->
<link rel="apple-touch-icon" sizes="114x114" href="touch-icon-iphone-114.png" />
<!-- Standard iPad -->
<link rel="apple-touch-icon" sizes="72x72" href="touch-icon-ipad-144.png" />
<!-- Retina iPad -->
<link rel="apple-touch-icon" sizes="144x144" href="touch-icon-ipad-144.png" />
The icon on Apple's site is 152x152 pixels.
http://www.apple.com/apple-touch-icon.png
Hope that answers your question.
TL;DR: use one PNG icon at 180 x 180 px # 150 ppi and then link to it like this:
<link rel="apple-touch-icon" href="path/to/apple-touch-icon.png">
Details on the Approach
As of 2020-04, the canonical response from Apple is reflected in their documentation on iOS.
Officially, the spec says:
iPhone 180px × 180px (60pt × 60pt #3x)
iPhone 120px × 120px (60pt × 60pt #2x)
iPad Pro 167px × 167px (83.5pt × 83.5pt #2x)
iPad, iPad mini 152px × 152px (76pt × 76pt #2x)
In reality, these sizing differences are tiny, so the performance savings will really only matter on very high traffic sites.
For lower traffic sites, I typically use one PNG icon at 180 x 180 px # 150 ppi and get very good results on all devices, even the plus sized ones.
I have been developing and designing iOS apps for a while and This is the best iOS design cheat sheet out there!
have fun :)!
Update:
For iOS 8+, and the new devices (iPhone 6, 6 Plus, iPad Air) see this updated link.
Meta update:
Iphone 6s/6s Plus have the same resolutions as iPhone 6/6 Plus respectively
This is an image from the new version of the article:
The relevant documentation on Apple's site, Specifying a Webpage Icon for Web Clip.
There is no need to put anything in the head of your document. If no icons are specified using a link element, the website root directory is searched for icons with the apple-touch-icon or apple-touch-icon-precomposed prefix.
For example, if the appropriate icon size for the device is 57 x 57, the system searches for filenames in the following order:
apple-touch-icon-57x57-precomposed.png
apple-touch-icon-57x57.png
apple-touch-icon-precomposed.png
apple-touch-icon.png
Yes. If the size does not match, the system will rescale it. But it's better to make 2 versions of the icons.
iPad — 72x72.
iPhone (≥4) — 114x114.
iPhone ≤3GS — 57x57 — If possible.
You could differentiate iPad and iPhone by the user agent on your server. If you don't want to write script on server, you could also change the icon with Javascript by
<link ref="apple-touch-icon" href="iPhone_version.png" />
...
if (... iPad test ...) {
$('link[rel="apple-touch-icon"]').href = 'iPad_version.png'; // assuming jQuery
}
This works because the icon is queried only when you add the web clip.
(There's no public way to differentiate iPhone ≥4 from iPhone ≤3GS in Javascript yet.)
Yes, bigger than 60x60 are supported. For simplicity, create icons of these 4 sizes:
1) 60x60 <= default
2) 76x76
3) 120x120
4) 152x152
Now, it's preferable to add them as links in your HTML as:
<link rel="apple-touch-icon" href="touch-icon-iphone.png">
<link rel="apple-touch-icon" sizes="76x76" href="touch-icon-ipad.png">
<link rel="apple-touch-icon" sizes="120x120" href="touch-icon-iphone-retina.png">
<link rel="apple-touch-icon" sizes="152x152" href="touch-icon-ipad-retina.png">
You can choose to not declare the 4 links above but just declare a single link, in which case give the highest size of 152x152 or even a size higher than that, say 196x196. It will always trim down the size for re-purposing. Ensure you mention the size.
You can also choose not to declare even a single link. Apple mentions that in this scenario, it will lookup the server root first for the size immediately higher that the size it wants (naming format: apple-touch-icon-<size>.png), and if that's not found then it will next look for the default file: apple-touch-icon.png. It's preferable that you define the link(s) as that will minimize the browser querying your server.
Icon necessities:
- use PNG, avoid interlaced
- use 24-bit PNG
- not necessary to use web-safe colors
In versions older than iOS 7, if you don't want it to add effects to your icons, then just add the suffix -precomposed.png to the file name. (iOS 7 doesn't add effects even without it).
I think this question is about web icons. I've tried giving an icon at 512x512, and on the iPhone 4 simulator it looks great (in the preview) however, when added to the home-screen it's badly pixelated.
On the good side, if you use a larger icon on the iPad (still with my 512x512 test) it does seem to come out in better quality on the iPad. Hopefully the iPhone 4 rendering is a bug.
I've opened a bug about this on radar.
EDIT:
I'm currently using a 114x114 icon in hopes that it'll look good on the iPhone 4 when it is released. If the iPhone 4 still has a bug when it comes out, I'm going to optimize the icon for the iPad (crisp and no resize at 72x72), and then let it scale down for old iPhones.
For iPhone and iPod touch, create icons that measure:
57 X 57 pixels
114 X 114 pixels (high resolution #2X)
For iPad, create an icon that measures:
72 x 72 pixels
144 X 144 pixels (high resolution #2X)

What are the correct pixel dimensions for an apple-touch-icon?

I'm not sure what the correct size should be.
Many sites seem to repeat that the apple-touch-icon should be 57x57 pixels but cite a broken link as their source.
Hanselman's and playgroundblues's comments suggest different sizes including 163x163 and 60x60.
Apple's own apple.com icon is 129x129!
See my related question:
How do I give my web sites an icon for iPhone?
It seems that Apple guidelines as of August 3, 2010 now include the "High resolution" images (for iPhone 4) in their "required" icon sizes.
Looks like we need to provide both a 57x57 and a 114x114 image now, as well as a 640x960 title image.
See Custom Icon and Image Creation Guidelines (Javascript required) which is part of a whole document:
iOS Human Interface Guidelines (2013; by Apple Inc; PDF; 26,3 MB)
Depends on how much detail you want it to have, it needs to have the aspect ratio of 1:1 (basically - it needs to be square)
I would go with the Apple's own 129*129
Apple specs specify new sizes for iOS7:
60x60
76x76
120x120
152x152
Whereas old sizes for iOS6 and prior are:
57x57
72x72
114x114
144x144
By the way, precomposed icons are deprecated.
As a consequence, to support but new devices (running iOS7) and older (iOS6 and prior), these 8 pictures must be present and the generic code is:
<link rel="apple-touch-icon" sizes="57x57" href="/apple-touch-icon-57x57.png">
<link rel="apple-touch-icon" sizes="114x114" href="/apple-touch-icon-114x114.png">
<link rel="apple-touch-icon" sizes="72x72" href="/apple-touch-icon-72x72.png">
<link rel="apple-touch-icon" sizes="144x144" href="/apple-touch-icon-144x144.png">
<link rel="apple-touch-icon" sizes="60x60" href="/apple-touch-icon-60x60.png">
<link rel="apple-touch-icon" sizes="120x120" href="/apple-touch-icon-120x120.png">
<link rel="apple-touch-icon" sizes="76x76" href="/apple-touch-icon-76x76.png">
<link rel="apple-touch-icon" sizes="152x152" href="/apple-touch-icon-152x152.png">
In addition, you should create a 152x152 picture named apple-touch-icon.png.
You might want to know that this favicon generator can generate all these pictures at once. Full disclosure: I'm the author of this site.
The official size is 57x57. I would recommend using the exact size simply due to the fact that it takes less memory when loaded (unless Apple caches the scaled representation). With that said, Rex is right that any square size will work
I don't think there is a "correct size". Since the iPhone really is running OSX, the icon rendering system is pretty robust. As long as you give it a high-quality image with the right aspect ratio and a resolution at least as high as the actual output will be, the OS will downscale very cleanly. My site uses a 158x158 and the icon looks pixel-perfect on the iPhone screen.
