### 4/5 — Pretty Funny!

*2026-07-07, version 7.0.0*

I used to play with my friends by mixing up some audio and then just playing it in different speeds or pitches to hear different voices! 😆 This is app is overall a well done! Thanks for creating it, it bought me back memories when I redownloaded it and played the files once more.

### 1/5 — Audio

*2026-06-09, version 7.0.0*

I can’t hear any sound on mine bro😢

### 5/5 — Decent but the time stretching messes everything up

*2026-05-30, version 7.0.0*

It’s a pretty decent app and now I know my audio in my tech time stretching is terrible if you don’t have the pitch linked to the speed, you’re gonna get these terrible artifacts so please switch to a pure sampling engine that will prevent the artifacts but also make sure there’s no distortion with when you slow it down really really slow because then that will also be something that messes up the audio other than that it’s a pretty good audio app

### 5/5 — Needs an update

### 3/5 — Great, can‘t screen capture on iphone though

*2026-04-03*

I love the simple and easy to use UI.
Feels so snappy - incredible, but how can I screencapture my live scrubbing?

As soon as I activate the Iphone inbuilt screencapture the Videoimage disappears..
