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!


Not bad thank you

Not bad thank you even the free version isn't bombarded with crazy ads so I think I'll pay for the paid version since it's the one time paid. I think it's worth it.

Terrible App

Its amazing how there are over a thousand 5 star reviews for this app and the developers don't respond to comments that point out the intelligible flaws with this app. The tuner is wrong more than half the time by far and changes every second even when I’m not even playing my guitar. If you actually want to tune your guitar unlike this app falsely advertises, use a different app, or even buy a new tuner because the price of that is still cheaper than the stress this app induces.
