About

Sayfa

Features
Read full description

Sayfa is a reading log, set like a book. You write down the pages, Sayfa keeps the count. LOG IN FIVE SECONDS Slide the page ruler to where you stopped and save. That's the whole habit. A GOAL YOU CAN KEEP Pick a number of pages you could read on a tired evening. Twenty lines fill as you go, and the day turns burgundy when you get there. YOUR BOOKS, YOUR SHELF Scan the barcode on the back cover and Sayfa fills in the title, author and page count. Finished books line up on a shelf by year, each spine as wide as the book was long. KEEP THE LINES YOU LOVE Underline a sentence in the book, photograph the page, and Sayfa picks out what you marked. Adjust the selection, fix anything misread, add the page and a note. Your quotes live on the book's page, newest first, with a mark on the progress bar where each one sits. Pages are read on your iPhone; the photo is never stored or uploaded. SEE YOUR PACE A streak, your longest streak, pages a day, a year of reading at a glance, and an honest estimate of when you'll finish at your pace. After two weeks, Sayfa starts noticing your patterns. A DAY WORTH KEEPING Reach the goal, finish a book or hold a streak and Sayfa offers a card for it: a title page, a colophon or a ledger. Share it, or save it to Photos. Or don't. Nothing is posted anywhere. QUIET BY DESIGN No feed, no followers, no library to curate. No ads and no analytics. One gentle reminder a day, and only if you haven't logged yet. YOURS Everything works without an account and stays on your iPhone. An optional account (Sign in with Apple or email) backs up your log and carries it to a new phone. Export everything as a CSV, or delete your account, from inside the app at any time. In English and Turkish.
