### 5/5 — 最好的chm阅读器

*2026-06-18*

本身已经是最好用的chm阅读器了，开发者还很热心的帮助解决了使用问题，太难得了👍

### 5/5 — 这个软件不能放大 没有放大功能

*2026-03-31*

刚买了去广告 发现没有放大功能 不太好用 作者感觉修改下

**Developer response:** 你好, 目前已经对移动端进行了适配. 按理来说是不需要放大的, 隐私就把放大缩小锁定了. 能讲一下您的使用场景嘛. 如果合适的话我可以解锁. 也可以通过 zhk1024@foxmail.com 联系我, 提供一些截图和深度交流.

### 5/5 — 非常不错

*2026-01-22*

非常不错👍，就是去广告的有点贵

### 1/5 — 字体无法改变

*2025-12-19*

如题

### 5/5 — 加油，！

*2025-10-24*

目前最好用的一个chm阅读器，希望能持续改进维护。

**Developer response:** 感谢支持, 如果您有什么好的改进建议欢迎告诉我. 我会尽力去做

### 5/5 — 终于有好用的chm阅读器了

*2025-08-09*

等了好多年了，以前IOS9的时候用CHM HD，后来升级到64位IOS后APP作者就不更新了，现在终于有好用的chm阅读器了。这个阅读器适配的好，大部分chm都可以阅读。使用后我提几点建议：
1.打开chm后目录显示乱码，如&#30707
2.有些chm文件页面上没有下一页和上一页，能否在下方按钮里增加上一页下一页，上一页下一页使用频率比上一章下一章高，章节可以使用目录
3. 有些chm文件不能正确加载css
4. 增加内购去广告

**Developer response:** 感谢支持, 稍后做优化. 关于 CSS 不能正确加载的问题, 是否方便分享一下文件呢?希望能够借助具体的文件调试一下问题. 我们的邮箱: support@mistar.tech
