Is not user-friendly.

It is not user-friendly, especially on mobile devices, compared to Bibliu.

Horrible lag

I have to keep exiting & re entering the app because every time I annotate, it takes up to like 5 seconds for it to even show up. Insane.

Doesn’t show on what page you are

I don’t understand why they prioritize showing your location on the book instead of showing the page. I literally cannot find from where I should start reading for my assignment because it doesn’t show PAGES, only location which is the most useless information.
