### 1/5 — Где звук записей! За что я плачу!?

*2026-01-26*

Исчез звук со всех записей. Некоторые могут открыться, когда закроешь и займешься повторно, некоторые даже таким образом не позволяют их прослушать!!!

### 2/5 — Very bad

*2025-12-15, version 1.3.2*

After the last update, the sound of already saved recordings disappeared! Guys, what are you doing? Your app is already the least trusted, and I feel like I'm the only one who believed in it, and now you're letting me down! I don't think there's a way to fix this epic failure. I can't even express how much you've let me down!

### 1/5 — 廣告覆蓋整個介面，而且檢測聲音會報錯

*2025-08-27, version 1.3.0*

廣告覆蓋整個介面，而且檢測聲音會報錯

### 2/5 — Saved recordings are not working

*2025-08-06, version 1.3.0*

Saved recordings without sound, only graph showing the dB. So you cannot replay the recorded Sound.

### 2/5 — Пропал звук записей почти всех

*2025-07-05*

Пропал звук на записях, которым и полугода нет. Даже букавльно этого месяца. Только сегодняшние еще со звуком. Куда обращаться за помощью на русском? Память айфона в порядке. Пробовала выгрузку приложения и переустановку, перезагрузку самого устройства. Всё бесполезно.

### 5/5 — Issue

*2025-05-26, version 1.2.8*

Good application , worked well, recorded even low volume sounds. But 3 days a go I faced a problem- there is no sound on all records I made before. Please help to resolve this issue, those records are really important for me.

### 2/5 — Wo sind die Soundfiles?

*2025-05-16*

Export via Email klappt nicht (Email ist ohne Inhalt), und wie kommt man an die Soundfiles ? Wieso sind diese wichtigen Dinge irgendwie ohne Funktion bzw. sonstwo versteckt?

### 4/5 — Good

*2025-05-02, version 1.2.7*

The update has some bugs - the text is not visible when renaming the recording and it has some errors when recording video, so you have to restart the application. When used, it drains the phone's battery very much. But overall, I like the app. Thanks to the developers

### 1/5 — 爛

*2025-01-19, version 1.2.6*

廣告真他媽的多，且遮蔽整個畫面影響操作，不建議浪費時間下載測試…

### 3/5 — Schallpegelmesser dB

*2025-01-01*

Ich vermisse die Möglichkeit die History zu exportieren und die Mitschnitte separat zu speichern. 😌
