Ratings and Reviews
Good, but needs updated
I like this app, but it often doesn't save my highlights and annotations. There are also glitches when I highlight, sometimes it wont allow me to switch to a different color without switching the color of my previous highlights. I would consider upgrading if I was confident the bugs were fixed. Some other features that would be nice are additional options such as underlining and ability to have changes made on 1 apple device to update on others that also have the CHM app installed.
Works. That's what's important
Simple app. Works well. Dropbox recognized it and sent a 70MB CHM format file to it without a problem. The file opened quickly and properly. Images and text are displayed correctly; all formatting is just like on my computer.
Free version allows highlighting in different colors and annotation. Not sure if these are embedded into the CHM file or kept elsewhere.
One complaint: the Table Of Contents button in the upper right corner of the window appeared grayed out when I first opened my CHM file. I thought the program was broken and I could only view the first page. It isn't broken; tap the grayed out TOC button and it opens correctly. It handles the nested CHM Table of Contents filing system well too. Nice app!
Free version has ads at the bottom of the screen. They appear to be text only, though, so it hasn't been too annoying. $7 to get rid of them is a bit steep.
Lite version capable on loading only 1chm file to give you a taste of the tool. File uploading is done by the app creating a server and entering the ip address of the server on the co outer to upload the file and hence it's done wirelessly. I would have prefered if the life version gave the option for at least 2-3 files to try in real time.
With Family Sharing set up, up to six family members can use this app.
