I bought this app to see whether I talk in my sleep or snore. The app works perfectly, recording every sigh, cough, and word. I set it on a 15 minute delay and then record for 7 hours. Its never failed to record the entire time or to play back. I keep it charged all night. I like the fact that the display goes dark but it still records. I use it every night and love it. The only thing that would make it better is a time indicator for utterances.
