iPhone icon refresh

321Run

321Run is a training and running app that's been on the AppStore for almost a year. It needs a refresh, on features as well as the icon, which is the first and most important thing people see.

I need something that stands out in a good way. I have tried not to use a running shape from day one because "everybody does it" so it's not the best way to stand out. But only suckers never change their mind. Prove me wrong.

This refresh shouldn't disturb current users of the app, which for the most part are casual runners, people who have started or have an intermediate level.

The goal is to make the app stand out amongst the incredible amount of icons on the health&fitness category of the AppStore. Depending on your country, it might be hard to find the app. Choose France in itunes if you want to see the app on the first or second page of that category.

You need to start from the original icon / background.

Don't use stock art. i don't want to have to licence extra content.

If you use the shape of someone running, that shape should go from left to right.

The ideas of movement, progress, fitness and activity are essential to the app. Choose colors appropriately.

Deliverables are a 512x512 px version, and a 57px version, at least in png. If you use Opacity, all the better. I don't want AI files or PSD.
