User reviews

Don’t buy. Doesn’t work anymore.

Same terminal concern as so many other reviews. Used the app for years.. iPhone 16 Pro; iOS 26+. Tuner stopped working. Wish they would fix it.

Tuner needle bug

The needle on the tuner does not appear. A prior review notes
Switching quickly from cords to tuner to get the needle to appear. This worked once for me. Hope it keeps working. App 2.6.0
iOS 26.2

Update needed

Guitar tuner no longer works. It's a shame because this was a cracking app.

Don’t work

I have used this application for years and loved it. The problem I had was keeping up with apple updates. Now as previously mentioned by another review NO tuner display on the screen. It was a good app.

Not updated since 2014

Skip this. It’s worthless. Was the pride of the AppStore at one point but neglect means it’s not usable.
