If you're expecting a Kindle level reader this isn't it. Loses access to content (even downloaded), doesn't sync well, loses highlights between readers and the website and loses track of where you left off even if you're not reading the same title across different devices or the website. Could be better but what other choice do you have?

First, I really like the O'Reilly service. They offer so much that no other technical learning platform does. Unfortunately, the mobile platform is a hot mess. It doesn't seem to play videos without wifi, unless they are downloaded. When I have enough mobile data signal that I can watch any YT video without interruption, these videos stop and studder so bad they are unusable. Books don't sync between PC and mobile. Lots more then I can post here.

This review is for the app itself, not the content. I mostly use it for audiobooks and... it's not great. The back and forward buttons on the mini player and the ones that get mapped to my headphone's buttons skip entire chapters, when it should just do 15-30 seconds like other audiobook and podcast apps. Also, on several occasions the audiobook will randomly restart from the beginning of the book and I have no idea where I left off.
