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.

Thanks for your feedback. Version 0.9.72 will fix the edge TTS and it’s being under review by Google Play review team. Please stay tuned.

I was drawn to Readest for the built in edge TTS, which sounds great. Much better than the default android TTS. I love the app, and I'm impressed with the functionality. Negatives: I'd love for the pages to turn along with the TTS. Currently, the book only catches up to TTS at the start of a new chapter. Also the app frequently crashes after exiting to another app and returning.
