Comments on Tuner - gStrings for Android

★★★★★ comrade boutchnasty · Oct 26, 2026

Been using g strings as my guitar tuner since I can remember at this point, worked well and have no reason to uninstall or switch.

★★★★★ Anshika Bhatt · Apr 3, 2026

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

★★★★★ 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.

Used to be great but doesn't detect notes properly any more even after reinstall so now doesn't work as a tuner. I wondered if my mic was faulty, but I found another app that works fine

★☆☆☆☆ Charlene Gumpolen · Oct 15, 2026

What did you people do to this app? It had never asked to record my audio, and it's not working as well anymore. You shouldn't have messed with it. If it's working don't fix it. This sucks To the creators of this perfect app. Please tell me this is a joke with major updates happening? I have been using this app for over 10 years! DO NOT CHANGE IT! I LOVE THIS APP IS FREE AND IT WORKS! Please keep it free

There's something wrong with tool, earlier it used to pic mic and tune flawlessly, after recent update, needle stuck, doesn't change note, doesn't pick up the mic tone properly
