LITERALLY THE BEST EREADING APP EVER. it even gets better when you purchase the pro version (which is affordable and worth it!!) because i get to sync my bookmarks, highlights, everything across multiple devices, and i get to customize the colors of the background, text and links in the books i'm reading. it's such a fun experience for readers who love to organize and personalize their reading materials. i was quite worried when this was gone from the store for a while, but it's back!

I've downloaded so many EPUB readers but this is the best one so far. It is easy to use, much more simplified yet it has everything I need. You can search words in the books, add notes, search them on internet, highlight them, change the sheet color and brightness etc. 10/10 would read again!

Everything is great apart from one surprising thing, title sorting. I don't know what i need to do in order to sort them properly. it goes like 1, 10 ,11 ,12 , 2 ,3 , 4. I've tried remaining files with single digits to start with 0, that didn't fix it either. Ultimately i believe the devs can make my life a lot easier with some tinkering or pattern recognition. Also no % to show how far you are in a book or the last book you read
