It's a useful app to have, but I think its UI is a bit too "conventional". If it is to be used frequently for memos, it should be simpler : just two big start/stop buttons, and the files named automatically (date+time) likes pictures on a camera... Also, a desktop widget would be really convenient.
Crashes constantly -- never been able to make any recording.
This is a needed function of the N900 -- Unfortunately this app isn't the way to get there
