Useless

Cannot get repeatable date using a tuning fork. Do not purchase!

DOES NOT WORK

DO NOT BUY THIS APP! I was trying to determine if the frequency on my keyboard was accurate (I can change the frequency on my keyboard). I’ve done this in the past with other frequency detectors. Even though you can actually HEAR the difference, this app does not register this change. For instance at A=440, the app says 441.39. When my instrument is tuned to A=300, this app says 441.39. Only when I tune to A=190 it changed to 417. So absolutely useless.

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.
