DownLow Recorder

With this stealth recording app you can record on the down low, once you open the app:
It vibrates shortly and starts automatically recording and the screen turns black, then the user can touch anywhere on the screen to stop and the user can touch anywhere on the screen again to start if desired, the phone will vibrate to indicate stop recording or start recording.
This app uses your built in mic and saves the file to your SD card as a 3GP file.
