I made an iOS version of Cop Recorder for the OpenWatch project: http://itunes.apple.com/us/app/cop-recorder!/id433040863?mt=... // https://github.com/chrisballinger/Cop-Recorder-iOS

There is no background support for recording, and Apple requires you to have a "conspicuous" recording indicator. I was initially rejected by displaying a black screen during recording.

Apple's own audio recorder will record with a blank screen, which is probably necessary to keep long lecture and presentation recordings practical. I wonder why people didn't/don't just use that. Of course the instant remote upload feature is convenient (and not yet possible from the voice memo app AFAIK).

There is now? That would be sweet! I had a sleep cycle app, but I couldn't lock the phone or switch the app in ios5, basically I would roll on it at night and turn it off... (you had to put it under your bed covers near your head).

P.s. to whoever voted me down, a response that I wasn't correct would have added to this discussion!

I'd imagine a totally black screen would do the trick in keeping the app hidden, or at least less obvious.

I'd just fake a login screen on the app's main page.
