About

Rabbit

Features
Read full description

Rabbit-Hole Steps is a pedometer story app inspired by the public-domain Alice books. Your real steps move you through a short Wonderland route of Tenniel-inspired scenes, curious signposts, and original English story lines. The free walk is intentionally compact: a two-day stroll through the rabbit-hole, the pool, the mushroom, the tea table, and the court. A one-time in-app purchase unlocks Looking-Glass World, a stranger walking board with chess steps, mirror-word clues, and small story puzzles. The unlock can be purchased from the main walk, and Wonderland remains free to walk at your own pace. Features: - Pedometer progress through a story route - A short free Wonderland walk - Optional Looking-Glass World unlock - Puzzle scenes inspired by mirror writing, chess movement, and nonsense verse - Public-domain Sir John Tenniel illustrations - Original English text written for this app - No account, no ads, no tracking, no location collection
