This is the best reader available. Far superior to Kindle and Nook. The Blitz Mode, which enables speed reading, has been an absolute game changer in how quickly I can cruise through books in a limited amount of time. a bunch of other features as well, which I haven't checked out yet.

Originally, I was annoyed that I could not use the app until I committed to a minimum usage time every day. I am not in the habit of committing to apps sight unseen. I thought I'd try the web version first to see if the experience is worth it, but David took the time to respond to my concerns. This app is definitely the easiest way to enjoy the ocean of books available online.

Thanks Maurice. As per your feedback, I've modified the onboarding process to allow people to make 'no pledge.' Solo developer here doing my best, so this kind of feedback is super helpful.

The issue with the crashing app is fixed. the variety of books are great. though I hope one day you will provide a student discount. while am at it, if I were to buy a book on playstore, will I be able to add it to the app?

Hey Kingsley, the student discount is something we can certainly provide in the future. If you have the ebook file itself (epub, pdf, etc), you can upload that to Lex. However, if your ebook is locked up in Play Store or another platform, you cannot read that on Lex. You can, however, log the corresponding reading activity on Lex.
