### 1/5 — does not work on macOS

*2024-06-05*

I am very disappointed because it does not work on my iMac.

### 1/5 — Went to trash

*2024-05-18*

Because it does not work on my Mac.

### 2/5 — Improvements needed

*2024-05-08*

The app's dark mode doesn't seem to adapt properly, and its functionality is too basic.

### 1/5 — Doesn't work on my M1 Mac

*2024-04-25*

Doesn't work on my M1 MacOS 14.4.1, other than displaying my current IP address.

### 4/5 — 不错的工具

*2023-09-14*

软件很干净，也很好用，就是不知道开发者是否能添加iPad横屏的支持呢？如果能加上横屏的话就更好了！

### 5/5 — 好评，辛苦开发者了，免费给大家使用

*2023-05-24*

好评，辛苦开发者了，免费给大家使用

### 1/5 — Buggy

*2023-01-25*

Some screens are not fitteed to look good and when attempting to reize (like the broadcast setup window) it crashes. I can't set the broadcast port.

### 5/5 — tcp客户端发送区能否加多gbk编码格式

*2023-01-19*

现有的没有，希望作者后续能够更进

**Developer response:** 已支持

### 5/5 — 良心小工具

*2022-10-22*

非常好用，五星好评

### 4/5 — Wrong network info

*2022-08-22*

This app is unaware of additional network interfaces that appear, such as the Ethernet interface when connecting a USB CDC ECM device.

Although it shows network info for only the Wi-Fi interface, it will receive data over the Ethernet interface.

It would be nice if this app had awareness of multiple interfaces.
