Comments on Perfect Guitar Tuner for Android

★★★★★ Jerry Meeks · Aug 24, 2026
One of the best online tuners I've used. I've run across a couple of tuners that were as much as a half step down from true concerto e-flat. All in all damn good app.
★★★★★ Jackson JilesVanMarteen · Aug 22, 2026
So far I love this app, although I wish you would add a twelve-string guitar
★★★★★ Robert Allen · Jun 22, 2026
I just dwnlded app. It offered premium service @ reasonable price. An X in the upper corner return to tuner. Free app still allows adjustment for tuning flat or sharp. I have not used the tuner but am very optimistic
★★★★★ Johnny Cook · Jul 16, 2026
I don't know exactly how to explain my experience with this tuner. All I can say is that the name pretty much sums up the word I would use, ...PERFECT!!! ;)
★☆☆☆☆ J R · May 6, 2026
Mind-blowing you have a 4.5 rating. Incredibly odd. Just finding out this app has been charging $15 every two weeks since install. Used it once. Did not meet expectations. Uninstalled. No mention of $15 a week.
★☆☆☆☆ Bobby Raymond · Jul 13, 2026
Oh my God, the ads are insulting. Constant.
★☆☆☆☆ Garrison Bailey · Aug 21, 2026
It says free then asks for money. That's not free. Stop advertising for free
★☆☆☆☆ James maddison · May 10, 2026
I don't trust this app at all. Multiple times I've caught it using the microphone while my phone is locked and on standby. That mic should not be active. Don't use this app if you value privacy even a tiny bit
★☆☆☆☆ Balint Kurnasz · Aug 3, 2026
Horrible adsfestation, spamming you with nonstop ads. Unusable
