I've had this app for quite a while...worked great until recently the decibel readings suddenly jump up about 10db after a short period of use. I don't usually pay attention to the number, but my graph readings shoot off the charts as well, so it really hinders the usefulness of the app.

The font needs to be larger on the frequency of numbers.

This gives me a good idea of what my system is pushing out at our gigs. Not super accurate with out proper calibration but worth the money.

Awesome!! Very accurate and useful! Used it to tune the room in a $100k home theater yesterday. Great app.

Doesn't work on the Razr... Just displays a white noise kinda wave. Input didn't seem to affect it

Not as feature filled as its big brother, but easily capable enough for amateurs like me.
