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!

Very easy to use, and no ads. I can also adjust the settings to my preferences, but I wish there's a feature that can mark the book finished or unfinished to help with the organization, although putting it to category section may work its not the same to other books that are already in other categories. Overall, one on the best that I have use.

ok so I love this app! super easy to use. I would've already bought the pro version (it's really affordable!) but there doesn't seem to be any way to reorder books in your library or in the custom lists. they automatically switch around putting whatever you read last on top. would love more control organising lists and renaming books once they're added please!
