Comments on Tuner - gStrings for Android

★★★★★ Treble Bass · Jan 26, 2026

This is a really good app, it works really well. I've been using it for years now. I am glad to have it and thank you. If you don't have a tuner you should get it. You should probably get it anyway just in case you lose your tuner. 😎

★★★★★ A Google user · Jan 29, 2026

I have been using this app for years and it's absolutely wonderful. There are a large variety of instruments to choose from. I even used it to tune my piano. Rock solid app that does exactly what it's supposed to do. Thank you.

★★★★★ Anshika Bhatt · Apr 3, 2026

Tells accurate frequency on violin or guitar, the best app for checking instrumental tuning

★☆☆☆☆ Diemo Gajeufsky · Sep 29, 2025

Was really good until now. Enforces ad-consent now. The point is: it had ads before, so I am not mad about that. But now I need to consent for giving away my data. A pitty...

No longer detects guitar, constantly stays on 49hz

★☆☆☆☆ TAFFY H. · Feb 10, 2026

Terrible tuner. I have a new Marimba and can't get middle C tuned. It goes up or down away from C no matter what I try. The name of the app should be changed, also.

Why is the app not catching the right frequency? Is there a bug?
