### 2/5 — Sound stops

*2026-07-29*

Somehow there is no sound anymore, it played just fine before but now there is no sound anymore even after restarting the app

### 5/5 — Love this

*2026-07-17, version 0.35.0*

great app i use this all the time super easy and there isn’t ads every 3 seconds absolutely the best audio/ file editing app on the app store

### 1/5 — とにかく使いづらい

*2026-07-14*

ポッドキャスト用のごく簡単な音声編集(切り貼り)のために使いたかったが、はっきり言ってゴミ。範囲選択をオンにしてもピンチしても波形の拡大と縮小が優先されてまともに選択できない、秒数指定をしようにもバーは分単位で表示されているのに何故か範囲選択のみ秒数表示、元に戻す／やり直すボタンがない、切り取ると何故か冒頭まで戻されていちいちスクロールで編集していたところにまでスワイプして戻す手間がかかる。UI勉強してない素人が作ってるならそう書いといてほしい。

### 2/5 — エラーばかり

*2026-07-11*

2年ほど使用してのレビューです。
機能は無料アプリとは考えられないほど豊富です。UIが最初は分かりづらいですが、この手のアプリを触った経験のある方ならすぐ慣れると思います。
しかし長めのファイルを読み込もうとするときや、カット･トリムなどの編集をしようとしたときなどに頻繁にエラーが吐かれます。以前は時々エラーが出るという程度でしたが、ここ最近は毎度エラーで全く使いものにならなくなりました。クリエイターとの連絡もメールのみらしく面倒です。他のアプリやパソコンでの編集をおすすめします。

### 4/5 — oggに対応する気は無いですか🥺

*2026-05-11*

機能は最高なんですけどoggが使いたくて、、、

### 1/5 — Funktional aber Daten Krake

*2026-04-16*

Ziemlich viele Berechtigungen verlangt diese App.

### 5/5 — That’s called freedom

*2026-04-01*

It’s free to use just like android, I was craving for this type of freedom in ios. Thank you so much creators.

### 5/5 — Thank you

*2026-03-27*

Thank you

### 2/5 — Could there be more of a guide?

*2026-03-09, version 0.34.0*

Very hard to navigate i recommend adding a guide

### 5/5 — The best

*2026-02-17*

If you are doing anything at all with sound on your phone you need at least this app from this guy. His products are the absolute best and actually free. So good you will want to donate to him. (Her?) them?
