3 stars: The best feature is that your books are sync'd between all devices and are even readable in the web client and you can easily upload your own ePubs. However development of the app has been severely neglected for many years now. My top requests: (!) Create a way to organize books into collections or shelves. (!) Enable continuous highlighting, like nearly every other reader. (!) Disable dictionary lookups, annoying.
3 stars: Great reading app, but I had night mode activated and it turned my screen permanently yellow, even when I was not using the app. I spent like a month without knowing what was wrong only to then figure it out that it was this app. It shouldn't work like that. If I wanted my phone to be yellow all the time, I could easily just turn on night mode in the phone.
4 stars: Very simple and clean layout, works just fine and dandy. I do hope it adds a custom shelves system, i have well over 1000 books and having a better way to sort them other than remembering titles and scrolling for a few minutes when i want to reread something. It would be a perfect 5 stars if it was added.
4 stars: Good app, but there is some weirdness with text anti-aliasing when reading e-textbooks on a Galaxy Tab S5e, and there's no obvious place to submit bug reports.
3 stars: There seems to be a problem again with uploading ebooks on the app. Uploads keep on failing again. Please fix this.
5 stars: Superb reading experience...
