Not very good

I just need an app that accurately tells me the frequency of s tone played through a speaker. This one kind of does that, for the first note presented to it, but fails to change its output when the tone changes. It sort of works if I keep shutting it down and restarting it, but that’s not very convenient. Also, it would be nice to have some documentation as to what the controls are supposed to do and what the display is supposed to indicate.

Don't waste your $2.99 like I did

This is a joke. I think it was designed by a 3rd grader. No features at all. I didn't read the reviews before I bought it and sure wish I would have. I never leave reviews but this time it's a must if that tells you anything.

Only shows certain frequencies

2 problems that make me want my $2.99 back:
1) I can't analyze frequencies without recording a file.
2) The frequency meter actually just shows you which note (A/A#/B/etc.) you are closest to, not the actual frequency of the note you are playing.
