### 5/5 — 使えるアプリ

*2026-06-25*

abリピートの微調整ができるようにして欲しい

### 5/5 — Life-saver

*2026-06-24, version 3.6.0*

I’ve listened to thousands of hours of religious content thanks to this app.

### 5/5 — Best app to learn a language

*2026-04-14, version 3.6.0*

Set the swipes to back and forward

### 5/5 — 리모트 컨트롤기능 좋습니다

*2025-11-18*

어학공부시 리모트 컨트롤 기능 있어서 앞뒤 스킵 가능해서 훌륭합니다  그리고 팝캐스트도 들을수 있고 좋습니다 안드로이드 버젼도 나왔으면 좋겠습니다.

### 5/5 — Excellent ap!

*2024-11-30*

Love this ap! I use it to improve my knowledge by speeding up the speed that I listen and learn! Impressive technology.
Thank you for this excellent ap.

### 4/5 — Fanatastic but please make sure all audio plaback is independant and can coexist

*2024-11-13*

Great speed modulating app for Apple Media Library content but please ensure it can coexist with other audio playback rather than pause and be either-orth

### 5/5 — Thoughtfully designed

*2024-06-04*

Wow! I wasn’t expecting to be so pleased. The features are very nice, love the extra options in the settings menu.

### 2/5 — It insists to order my playlist in ways that doesn’t make sense

*2024-04-09*

I’ve it many times and am very frustrated. If I upload several sound files, this all would order them on ways that looked totally random to me. And it seems that I have on way to reorder them. I have upload them literally one by one in order for them to stay in the order that I need them to. For they, I hate this app!!!!

### 3/5 — More precise audio speed options?

*2023-12-10*

This app is pretty good, however it would be better if the speed options did not change by a twentieth. (1.05, 1.1, 1.15, etc.) Can it be more precise be hundreths? (1.01, 1.02, 1.03, etc.) Or better yet, thousandths! (1.001, 1.002, 1.003, etc.) Thanks!

### 1/5 — Not useful

*2023-09-25*

Won’t give you the ability to vary speed on an entire playlist, as in”play this list of fiddle tunes at 110% speed.” That’s the only reason I tried this. There are much better apps out there to speed up and slow down music on single tracks, which is all this does with sliders that are not very granular.
