ZTF Books

ZTF Books is your digital Christian library — the writings of Professor Zacharias Tanee Fomum and other trusted authors, over 1,000 titles in 100+ languages, to read and to hear on every device.

FREE TO START
• A welcome voucher for free books when you sign up
• 100+ books that are always free — no card needed
• Free 3-day trial with unlimited access to the full library

READING CHALLENGES
• Join a time-boxed challenge and read toward it alongside everyone else taking part
• Three kinds of target — any qualifying books you choose, a list chosen for you, or books from one series
• The rules are on the table before you join — the dates, what counts, and what others can see
• Follow your own progress ring, with the group's total beside it
• Start a private challenge and invite the people you read with by link, code or QR code, or join one by scanning its QR code
• Private by design — others never see which books you read, and there is no ranking

BUILD YOUR LIBRARY
• Shelves — organize your books into your own named collections
• Wishlist — save titles to read or buy later
• Favourites — keep the books you love close, with swipe-to-remove
• Group your library by series and read every book in order

READ IT. HEAR IT.

• Highlight, bookmark, and look up names and terms on Wikipedia as you read
• Search the full text of the book you're reading — tap any match to jump straight to it
