### 1/5 — 用不了

*2023-06-07*

购买购买后不能使用

### 2/5 — No shut down

*2026-01-07*

The app will not allow you swipe and shut it off in new iOS, have to shut down iOS and reboot in order to kill the app, hmmmm don’t like that

### 4/5 — Great for me

*2016-07-08*

I just started using this app and I can see what the rave is all about. I am very happy with it, it is easy to use, simple design and easy setup.

### 5/5 — Great app

### 5/5 — Fun and useful

*2016-07-14*

This is fun to play with. I'm not going to tune my piano or calibrate my audiometer with it, but it's useful to see what the main frequencies are in everyday sounds and noises. Its also a great conversation starter when you start whistling into your phone. Very cool app
