Nothing is working 
Why

### 1/5 — Absolutely horrible

*2023-06-02*

It sounds like a microwave

### 1/5 — Waste of space

*2022-12-05*

It doesn’t work. 
It’s still doing the same thing people complained about years ago.

### 1/5 — Worthless app

*2022-04-08, version 1.10.0*

Only 4 notes available! What the heck

### 1/5 — Not good

*2020-12-23*

The adverts made the sound glitch, so I ended up using YouTube.

### 1/5 — Screen stayed blank???

*2020-04-17*

I got this app so I could tune my out-of-tune cello. But when I tapped the notes nothing happened. The screen stayed the same as when I had first opened it. It didn’t even do anything as I played any notes. Please fix this.

### 5/5 — Wasn’t bad at all!

*2020-04-10*

It worked every time and I liked how sharp it felt to the touch as well!

### 1/5 — Just plays notes not a tuner

*2019-10-12*

The expectation of a tuner is that it listens and tells you to go higher or lower. This just played notes and not well to tune by ear. I kinda want my $0.99 back
