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 • Readers who like keeping notes and impressions of each book

Verdict
The clearest difference is iOS requirement: Simplist at 15.0 against Yondazo's 18.0. On price, ads, in-app purchases and device support there is nothing between them.
