### 5/5 — Great tuner

*2023-12-28*

Great for guitars also. God for setting intonation

### 5/5 — Good

*2023-10-19*

Works for guitar too

### 5/5 — Awesome strobe tuner!

*2023-07-20*

Super lightweight app, free, no data collected, quick, straight to the point, very clear and easy to use.

The only feedback i could provide is, I would love to have an option to put the controls on the top  of the screen, or to let the app rotate if I hold the phone upside down, so i could use it easily even when i point the phone microphone to what’s in front of me.

### 1/5 — Horrible

*2022-03-23*

In a dead silent room the wheel was spinning outta control!!!!, I tuned a note middle C dead accurate with a full size strobe then attempted to use this app to see how well it performed. This app is useless. Except if you like watching the pretty interesting visual effect of the never ending black and white hashes

### 5/5 — Great Tuner

*2022-01-26*

It’s a Free Strobo Tuner that works well.

### 1/5 — Not fully developed

*2021-10-06*

This app only works with inner cell phone microphones. It won’t work with the dongle (iPhone 8) - it immediately freezes. Needs more work.
