Colouring Bookshelf is a personal tracker designed for colouring book enthusiasts who want to organise their collection, track their progress, and plan out their buddy colour sessions!

Your collection, your way
Add your colouring books and track everything that matters — physical or digital copies, whether you've started them, how many pages you've coloured, and how close you are to completing each book. Add cover photos, keyword tags, and author details to make your library feel truly yours. The calendar feature lets you keep track of all your upcoming Buddy Colours so you never forget another page. Track your stats such as percentage of each book completed, percentage of total books finished and more. All data lives on your phone, controlled by you.

Track your progress
See your colouring journey at a glance with detailed stats — total books, pages coloured across your entire collection, usage breakdowns, and a progress bar showing how much of your total pages you've actually coloured.

Plan your projects
A built-in calendar lets you plan colouring sessions, buddy colour events, and themed projects. Add events to specific dates with notes, and see everything coming up in a single upcoming events list.

Share and compare with friends
Share your book list with fellow colourers via WhatsApp, Instagram, or any messaging app. Export your full collection as a JSON file and compare lists with friends to instantly see which books you have in common.

Your data, your device
Everything is stored privately on your device — no account required, no internet connection needed after the first load, and no data ever leaves your phone without you deliberately sending it. Your collection is yours alone.

Personalise your experience
Choose from six built-in colour themes or create your own with custom colour pickers. Make the app feel like an extension of your colouring style.

Back up and restore
Export a backup of your entire collection and restore it any time. Perfect for switching phones or reinstalling the app.
