This app is not for recording or importing long 30-minute sessions. They advertise the Ferrite app for that. This app will eat up huge chunks of storage and crash if you cant hook up to itunes on a computer once in a while to delete old cached data. You can also delete and re-install the app occasionally to erase built-up hidden data. Aside from that, this app works even better than audacity because silence is really silent, and you can zoom in and out on a track even while its playing. My recording studio has shrunk down to a tiny closet and is quite portable now, thanks to this app and my ipad. Itll be nice someday when the app will be able to output as mp3. That will save a couple of steps.
