Simple. Lets you test specific freqs, what more could you ask for? Great for calibrating pass filters on speakers

Dude seriously. Change the seekbar for frequency selection to a log scale. It only takes one or two lines of code in your onseekbarchanged listener.

Needs to be able to below 10 and to fine tune. Nice free app. Perhaps offer paid version with addition features

5 stars if you add the option to fine tune the frequencies, eg. 591.7 Hz
