Customer Reviews

Solid app

The app does a nice job of navigating a chm file. One of the best on iTunes.

The only shortcomings I would like to see addressed is the lack of a search feature and the capability to add notes from text that is highlighted.

While those features would be nice the program is very solid as is.
I have never experienced a Christ, even with huge files loaded.

If you need to read chm files, this is the one!


Easy to use. Way better than the more expensive ones...
