PLEASE UPDATE – Slow Down Music Player Review

I think it's really a shame that you pay for the full version of an app, and the creators do not make sure that it continues to work, with all the updates for the iPhone. I am a musician who used this app for studio purposes. I paid for the full version of the app, but haven't been able to use it in almost 6 months. Please update!!!
