App Icon Resizer (AIR‪)‬ 4+

This is an excellent and straight-forward app icon generator - it even makes the imageset for you!

This app is short on documentation, but it works like this:

1. Choose target devices

2. Drag a PNG image that's at least 1024x1024 onto the box. It won't warn you if your source image is too small, nor will it upsample it for the larger icons.

3. Click "Generate" or "Re-Generate"

3a. If it's the first time you're using the app, it'll ask for a target folder in which to save the imageset (although it doesn't tell you this).

3b. The idea is that you're supposed to pick an xcassets folder at this point (it also doesn't tell you this), which in theory, is super convenient.

3c. Once you choose a folder, it'll never prompt again. And there's no way to change the designation directory later on. This means that if you have more than one app, you should chose the Desktop or Downloads as a destination.

Anyway, 5 stars for execution, minus a star for 3a,b,c above.

I really love this app. It makes my work easier to resize app icons. However, there is just one really minor thing you can add on. Making app icons for Mac would really help and posting an update would be awesome.

This is amazing, was frustrated with the app icon design stuff as it was for my first app and this just made my day a whole lot easier, I know there are web apps for this kind of thing but I always appreciate having a native app and this does the job well so thanks for your app and hard work.
