Pretty decent, especially with the new iOS update.

This app was okay before the most recent iOS update, but now its even better. With the iOS 7.0 update, the app now records without the red headline on the top of the phone when the phone is not in active use. This makes the recording completely covert, whereas the red bar was visible before. I dont know if this is an unforeseen flaw with the new update, but I like it. Im in law enforcement, and I record every interaction that I have with the public. And let me tell you something, if youre a citizen, you must do the same with your interactions with the police. This is the perfect app for that. Anyway, the app gets only four stars because it doesnt yet feature the option to trim files. Add that, and Ill gladly upgrade the rating to five stars.
