### 5/5 — Can you support videos mp4s?

*2025-02-08, version 1.03*

Tried videos but doesnt suggest the app to open them when sharing

### 1/5 — Bugs

*2024-02-04*

O que está acontecendo com o app para iPhone 14 Pro? Está dando erro e não reconhece os áudios!

### 2/5 — A good app but…

*2023-07-04*

I really like this app, which lets me change the speed and key of a piece of music. However, I find it very incomplete, which is a shame since I paid for it. Here are the improvements I'd like to see:

- Being able to listen to music in the background without it bugging all the time
- Real management of music detected by the iphone
- A new design
- Better music management (add music more easily to the app, add album art)
- resemble a real music management app, but with independent settings for each track
- The ability to create playlists

### 1/5 — Глючить ваше програма

### 2/5 — Can’t believe this.

*2021-10-19*

I paid $7 for this app and it’s messing up saying my microphone isn’t set up correctly after only recording like 10-20 something recordings vs the non-pro which didn’t do that but that version has messed up too. Please update this lousy app. PLEASE!!! Why is it saying my microphone isn’t set up correctly when I can record on other apps!!??

### 1/5 — Nicht das Geld wert

*2021-10-17, version 1.03*

Die beschriebenen Funktionen sind gegeben, aber der Klang ist eine pure Katastrophe. Vielleicht liegt’s an meinem iPhone 13 pro. Aber es klingt wie ein defekter Lautsprecher. Habe mich wirklich erschrocken. Es ist definitiv nicht empfehlenswert. mm_aus_n

### 3/5 — Нет проигрывания в фоновом режиме.

*2021-06-09, version 1.03*

Хорошее приложение, но за такую цену очень плохо, что приложение не работает при блокировке экрана. Очень мешает при работе с музыкой.

### 2/5 — Fix It!

*2020-04-23*

Great app if you don’t mind it constantly stopping in the middle of a song.

### 5/5 — Fantastic app

*2020-04-14, version 1.03*

Used primarily for audio, this app is great. Does exactly what it says. Adding songs is a bit cumbersome but I suspect this is an Apple limitation rather than theapp.

### 2/5 — Complicated

*2019-12-17*

7 dollars gets you any song you want with zero adds. HOWEVER, sound quality does not change in the slightest regardless of which version, inconsistency when switching apps so music may suddenly shut off. Marking system very touchy, and just isn’t worth the price point especially with someone like me who constantly uses it for either practice or casual fun.
