Excellent app. Found my books immediately. I gave this four stars for two reasons. First, the book contents, etc. are on the RIGHT side. When turning pages, you can get that information, which distracts from reading. Second, no dictionary. The pages turn beautifully, except when you get the table of contents by mistake. Taking notes is a breeze, and it appears that copying selected text - for insertion into a school paper, for example, is available, but I did not test it. I really wish there was a dictionary option. Leaving your reading to look up a word - might as well be reading a "real" book. Otherwise, I really like this app for reading epub.

Very good! This is an excellent quality e-reader and it's got a nice minimalist interface that doesn't get in the way. I use the Pro version, but it's still missing the single feature that I need most: Backup of epub files to Google Drive. The problem is that a lost phone is still something of a disaster when there's no backup of the epub's themselves. The only other thing it needs badly is background preloading of the next page. Otherwise, it's an excellent reader. Much better than 90% of what's out there.

Great, lightweight app. Never crashes, never loses my page. Books are automatically detected, even when moved around. It doesn't ask for extraneous permissions or waste resources on unwanted features. I just wish I had more control over the naming scheme. Regardless of file name, the display of the titles and authors is beyond my apparent control - and as a result they are inconsistent, which is especially problematic while sorting. This is only somewhat bothersome, though. Usually the metadata is pretty clean.
