This app is very well made. I can rest easy now knowing I dont have to fret if I forget my tuner at home! (Pun intended.) In fact, I dont use my standalone tuner. It is very accurate and deadly simple to use. This app works best for guitar, but Ive used it on other string instruments as well.
It doesnt work too well for piano at high or low scale, but then again, who tunes their own piano.
I recommend this app too every musician I know. Very impressive!
