Do NOT Purchase
Dont waste your money on this app. It does not work. First you have to use record mode if you have an iPhone 5. Record mode is an in app purchase. The record mode does not work. It lets you press the record buttons but when you go to playback you only get a random 10 second clip each time. You dont even hear sound for the full 10 seconds of the recording. Then the app crashes. Waste of time and $$$.
