### 1/5 — 闪退

*2022-09-24*

最近一直闪退

### 5/5 — Lite but great

*2021-01-07*

I use this app to read a chm file I compiled many years ago. Compared with a popular 4-star ePub/chm reader, this app is much better. This one displays embedded HTML elements normally, whereas that higher-rated app lost many linked images.

### 1/5 — wastes screen space on iphone X

*2020-11-02*

not even talking about the notch, it just wastes so much screen.

**Developer response:** Hi,
ChmPlus has already been updated for the current iOS/iPadOS!
Thank you!

### 5/5 — 挺好，刚开始不知道怎么使用

*2020-02-01*

挺好的一款chm格式阅读器
