It improves with every update, but it is really fantastic. The plug in works perfectly, lifetime subscription for not much if you want it, or free use for tons of epubs. Just reading in the app itself is excellent on eink devices on android. All the options I could want. Only change I would ask for is being able to tap the progress bar at the bottom and be able to cycle through all the options instead of doing it in the menu. great work guys.

I only use this for mobile as I have no need to read on my computer. If you are just using this to read, this app will fulfill that purpose. I have a few issues with the app. First off, adding books takes forever especially when you have quite a collection downloaded. 2nd there are quite a few issues with the TTS, in 3 different books, the TTS changes from English to French for no reason, you also cannot change the TTS voice, and it does not update the book on where you are at when you finishTTS

This is perhaps my favorite eBook reading app. It's not the most intuitive but it crams in a lot of functionality in a clean way. It also has one of the best TTS features. This latest version 0.9.71 seems to have broken the Edge TTS voices, which unfortunately are the best voices available. If your phone has other TTS engines, those probably will still work. I'm hoping for a fix to the edge TTS voices.
