Icon for iPhone app

Repetitions

I am an independent software developer about to release my first iPhone app.

Repetitions is a simple app that helps you perform physical exercises, set up by yourself or your physiotherapist. Unlike other apps it is not specifically designed for use in the gym; you can use it both with and without weights and other aids, in fact it's flexible enough to be used with just about anything that requires timing. It doesn't come with any predefined exercises, you're free to define your own.

* Repetitions uses sounds to inform you when you should exercise or rest, so if you have a first generation iPod touch you will need to connect external speakers to get full use of it.

Two icon sizes needed:
- 512x512 (for the AppStore/iTunes)
- 57x57 (for the iPhone main screen)

Both must be in PNG format.

The icon should reflect repetition, but should not contain any weights or other gym equipment. It should be simple, and look good in an iPhone screen with 19 other app icons. It should not contain any text, but numbers are OK.

Here are some screenshots to give you an idea of the UI of the app (http://www.quicksnapper.com/karemorstol/). And a video (http://nottoobadsoftware.com/Repeti…itions.mov).
