Ratings and Reviews

Great app

Bevan Y

Great free trial app for all the medical chm textbooks. Great table of contents, which helps enormously with some of the very big textbooks. Seems to render tables and pictures well, when you fiddle with some of the settings. Much better on the iPad than iChm, although iChm has a desktop version, so you can see what your chms might look like on your computer before you load them onto your iPad. I upgraded to the full version, so I can load more multiple chms. Well worth it. Tried to convert chms to epub format using Calibre, so iBooks could read them, but gave up, as it was just too difficult, and the converted looked ugly.

Almost good, but not worth the price without improvements.

Renders well, and has a nice enough reading interface with full-screen, but the file management really lets this app down. It has no way for working with documentation sets consisting of multiple CHM files, no sub folder support or way to list files that aren't explicitly in a collection (you only get collections, or "All Files"). The app doesn't handle zip files so there's no way to get a structured collection of files in to the app.

Great app

This app is awesome. Been looking for a way to read my files, then found this. Clean, easy and simple.
It's a joy to use.
