EPUB
The most widely used format for digital books. Reflowable, so text resizes to fit any screen — phone, tablet or desktop.

Wide format support
Bring the books you already have
Fifteen formats, from the ones everybody uses to the ones your university library still hands out on a memory stick. If it is a book, we will open it.
Fixed layout that preserves exact design, fonts and images regardless of screen size. Ideal for textbooks and graphic-heavy books.

The catalogue
New titles every week
Built for real conditions
The network will drop. Your book should not.
Most reading platforms are designed for fibre and flagship phones. This one is designed for the bus, the boarding house, and the last week of the data bundle.
Works at 2G
Pages are built to arrive on a slow connection. Covers stream last, text arrives first.
Read offline
Download a book once and it stays on your device. No signal needed to open it again.
Light on storage
Built for phones that are already nearly full. Downloads are compressed and removable per title.
Picks up where you left
Your place, across every device you sign in on, synced as soon as you reconnect.
One platform, four ways in
Whoever you are in the chain
