About

KRIZ

Features
Read full description

KRIZ is a reading diary, not another book catalogue. A catalogue answers “what have I read”. A diary answers “what happened to me while I was reading it”. KRIZ is about the second one. Three sections instead of lists Past, present, future. A book lives through them in turn, as it should. A diary you assemble yourself Quotes, thoughts, questions, observations, characters, things to explore after the book. Switch on only the blocks you need — the rest stays out of the way. Nothing is required: marking a book as finished is enough. Search your own words Remember the quote but not the book? A few words will find it. A book is added in a second By title, by author, or by scanning the barcode on the cover. What to read next The randomiser picks from the books you saved, from your shelf, or offers something new — from a selection of two thousand books with covers, descriptions and readers’ ratings. Cards for stories Eight ready-made looks. You tick what to show — cover, quote, rating, dates — and the app composes the card. Month summaries How much you read, what you liked most, which book turned out the longest. A fortune for the day One short line — a reason to open the diary even on a busy day. Import from Goodreads and StoryGraph Ratings, reviews, dates and shelves come across with the books. Free forever The whole diary: any number of books, entries and shelves. Search through your own words, barcode scanner, sync between devices, import, light and dark themes, story cards. What came free stays free. The KRIZ subscription adds Quote scanner: photograph a page, the text is recognised and you can fix it before saving. Voice notes. Photos for a book. Ambient sounds: rain, a library, a café. Every card template and extra appearances. The first seven days are free. Your entries are yours The diary lives on your phone and works offline. An account is only for syncing between devices — and it is optional. Backups are saved as an ordinary file. Ukrainian, Russian, English, Greek.

About

Sayfa

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.
