### 1/5 — Trash

*2025-11-22*

I would not have even put this on the App Store

### 1/5 — Beware! App is NOT free.

*2023-03-24*

I installed this on my iPhone and Ubuntu Linux and immediately upon launching tells you to visit a website to download and pay for a license. Use KDE Connect instead because it’s actually free and open source.

### 3/5 — 苹果设备总是抽风

*2022-10-05*

软件很好，在windows和Android上很好用，但是iPhone总是搜不到其他设备，希望作者处理。
