I lost my guitar tuner and I was like sOooooooooooooo frustrated because my guitar sounded SO OFF TUNE! And I could play for any friends or family(which everyone wanted because they needed it during Covid) so I looked up “guitar tuning apps” and this came up! It’s perfect! My guitar sounds great and now I can inspire people with my music again! Thanks so Much!

This is the best guitar tuner I’ve tried! Amazing, fast, and accurate. This is a must have for everyone, not just those learning to play guitar.

I like everything about it except for

Can you please remove the “try our ear tuner” as please? I have paid to get rid of ads and this is an ad a d it really ruins the otherwise superbly simple abs effective app.

I’ll come back snd give you the other 3 stars once that button is gone. Add a menu button on the corner snd hide it there.

Thank you!
