And kinda fun too. This is one app that genuinely and reliably delivers. All players would do well to try it. My guess is that most would keep and use it as much as I.

I love this app I am so happy I found out I used to use it to tune my guitar but now I use it for I used to go to guitar lessons but they didn't teach us any chords so I am very happy I found this app because if I didn't I would've gave up . 100% would recommend 😊😊🎸

Kac B on 7/19/2017
My daughter is learning guitar and before we found this app we had to wait the week before we saw he teacher to tune it. Sometimes it would get so out of tune she wouldn't even want to practice. Now she's learning to tune with this app. Love it.
Great tuner!

Rebbi Ofer on 7/18/2017
I have been able to tune my Ukulele and guitar quickly and easily as can be.
It works well
Eli.2337 on 7/18/2017
I really like this app, it works well for standard tuning, and I have it whenever I need it. However I would like to point out that it does not tune in anything except standard. I play a lot of songs in drop d and drop c and drop d flat. I would love it if I could tune my guitar to those so that I could play those songs whenever.
Bily Bob F on 7/18/2017
Perfect app to tune when practicing at home. Quite accurate!
Great tuning app!

So great. It's much more precise than our electric tuners for our guitars and ukelele.
P good app
ThatCrow on 7/17/2017
I just recently decided to try and learn how to play a ukulele and this app works great. My favorite part is that I can either let it try and detect the string I'm adjusting or I can select a specific one. 👍🏻
Top notch
