Does not work anymore

Used to work but now crashes when the files folder is opened. Cannot read anything anymore.

Hands down, not the prettiest, but most functional

After purchasing the more expensive option, and running into limitations such as no "Open In" functionality and incorrect formatting or not enough formatting of text options, I stumbled across this app. This app gets most of it right and I will use it for the time being. It's also nice to see that it has been developed sometime during 2013 at least and not still stuck in 2012.

The not so great app I refer to above is ChmPlus Pro which was $6.99 which I regret.

Update app can't open ePub files which open great in iBooks or other apps. Plus there are minor bugs.

Needs update

The default text size setting fails and no matter what I set the font size at using +/- scrolling up/down only scrolls a third of my finger movement and scrolling right/left is like a difficult computer game since it only works after many attempts. It is still the best CHM reader since it has normal search functions the others skimp on, bizarrely. Having to use landscape mode due to lack of good word wrap in portrait mode means I can only see a few lines and then the slow vertical scrolling becomes real torture. Still searching for a better app I'm afraid.
