Worked fine then iPhone 5 came out...

I own an iPhone 4 and ever since the app update for the new iPhone 5,when you finish tuning, you cant go back to the boost gauge... You cant adjust the boost pressure, sensitivity, volume, or boost warning light. I used to play around with this app a lot and then all of a sudden this happens.
