Chapterpillar is a cozy reading tracker for kids and families. Log a finished book, and your caterpillar gains a segment. The more you read, the longer Pip gets.
Any book counts: picture books, chapter books, bedtime stories read together.
Scan the barcode or type the title, give it stars, tell Pip how it went.
Every book adds a segment. Hit milestones and Pip somersaults, sprouts wings, and earns a crown.
Each reader grows their own Chapterpillar. Segments are color-coded to the books they came from.
Somersaults at 5 books, butterfly wings at 10, Library Monarch at 20. Always a next adventure.
Profiles for every kid. No emails, no passwords, just a name and an avatar.
Every logged book lives on a cozy shelf, ratings, reading journeys and all, to look back on for years.
Point the camera at the barcode and Pip fills in the title, author, pages, and cover.
Editing, settings, and the book shop live behind a family PIN. Kids just read and grow.
This is what finishing a book feels like in Chapterpillar.
Yes. Chapterpillar is free for families. If a grown-up buys a book through our recommendation links, Amazon pays us a small commission. That's the whole business model.
Anyone who reads or is read to, from picture-book listeners to chapter-book devourers. The worm doesn't care how long the books are.
Yes! One grown-up account, a profile for every reader (grown-ups can have worms too). Kids never need emails or passwords.
No ads, no trackers, no selling data, no kid accounts, and real export & delete buttons. The details are in how we keep Pip's secrets.
Free for families. Set up in two minutes, and the first book is the best one.
