About this app

Kamigokochi lines your books up on a beautiful 3D bookshelf. The book you read on Kindle, the paperback at the back of your shelf, the one you skimmed on a reading subscription — whatever the platform, every book you have read comes together here. ■ A real 3D bookshelf, one spine at a time Watch your spines line up just like a real shelf. Tap a book to pull it out. Haptic feedback and sound effects recreate the feel of running your hand along a paper bookshelf. ■ Add a book with a quick scan Just point your camera at the ISBN barcode. You can also search by title or author, or add books by hand. ■ Update your reading progress anytime Enter the pages you read today in a tap. A progress bar shows the pages you have left at a glance. ■ Record each book from start to finish Save the day you started and the day you finished to see how long you spent with each book. Reach the last page and a celebration marks your finish. ■ Leave a note on every book you read Write down your thoughts the moment you finish. Saved with the finish date, every book becomes a memory you can keep. ■ Capture the lines that stay with you Jot down the quotes and passages that catch your eye, tagged with their page numbers. Add as many as you like per book, and sort them by page or by date to look back later. ■ Your reading, on a calendar A heatmap calendar visualizes how much you read each day, along with your reading breakdown and your streak. ■ Organize with multiple shelves "Novels," "Tech," "To Read" — create shelves however you like and sort your books your way. ■ Your data stays on your device No account required. Everything is stored on your device, and you can export or restore anytime with a JSON backup. ■ Premium (one-time purchase) - Unlimited books (free plan: up to 50) - Unlimited shelves - Remove ads - Data backup

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
