## What is Yondazo?

Yondazo is a reading log app that helps you track every book you finish and reflect on your reading journey from three different angles: monthly totals, year-over-year comparisons, and all-time growth. On Apple Intelligence-compatible devices, you can also get on-device AI insights into your reading habits — fully private, fully local.


■ THREE CHARTS TO VISUALIZE YOUR READING

See how much you've read this month with the monthly bar chart, compare this year against last year with the year-over-year view, and watch your reading habit build over time with the cumulative line chart. Switch between the three views to look back on your reading journey from every angle.


■ AI READING INSIGHTS, PROCESSED ON-DEVICE

On Apple Intelligence-compatible devices, on-device AI analyzes your reading habits and surfaces patterns you might not have noticed on your own — favorite genres, go-to authors, and your natural reading rhythm.

Everything runs locally on your iPhone. Your reading data never leaves the device and is never sent to any server. It's private AI reading analysis — with nothing ever sent to the cloud.

* On devices that don't support Apple Intelligence, you can still explore your reading trends through detailed statistics.


■ NOTES, RATINGS & GENRES FOR EVERY BOOK

Jot down your thoughts after finishing a book, give it a 5-star rating, and tag it with a genre. Each entry becomes part of your personal reading journal, so you can revisit what you read and how you felt about it. Bookmark your favorites to find them again with a single tap.


■ A BEAUTIFUL BOOKSHELF, ALL YOURS

Every book you add appears in a beautiful cover grid — a bookshelf that's entirely yours, ready to browse anytime. Prefer a cleaner view? Switch to list mode with a single tap.


■ ADD BOOKS IN SECONDS WITH BARCODE SCAN

Just point your camera at a book's barcode. The title, author, publisher, and cover are added automatically — no tedious typing required. For older titles without a barcode, you can search and add them by title.


■ YOUR DATA, SAFE AND PORTABLE

Your reading history matters. That's why Yondazo gives you the tools to keep it safe.
• Full backup and restore (JSON format)
• Seamless data transfer when you switch devices
• Automatic migration from older versions


■ WHO IT'S FOR

• Readers who want a simple way to log the books they finish
• Anyone curious about how many books they read each month
• People who like comparing this year's reading with last year's
• Readers who enjoy reflecting on their habits through data
• Anyone who wants AI to help them spot patterns in their reading
