Update broke this

This was a great app until the most recent update. It will no longer work on my iPod 4 (which I use for all my training apps) even though it claims to work on IOS 6. It looks like it is going to open and then it crashes.I hope they fix it, but until they do the app is useless. Can I have my money back? If they are not going to fix it, why dont they offer an older version to IOS 6 users?
