Oz Steps
Read full descriptionHide full description
Oz Steps is a pedometer story app inspired by the public-domain Oz book. Your real steps move Dorothy along a short story route from Kansas to the Emerald City, with silver shoes, curious companions, and small collectible relics appearing as your step count grows. The first half of the walk is free and ends at the green gate. A one-time in-app purchase unlocks Return Road, the second half of the route: the Witch's road, the Golden Cap, Glinda, and the final walk back home. The paid route is designed as a story extension, not a subscription or external service. Features: - Pedometer progress through a literary story route - A free first-half Oz walk - Optional Return Road unlock for the second half - Original English app text written for this app - Public-domain book-inspired Oz framing - Silver shoes, not movie-specific ruby slippers - No account, no ads, no tracking, no location collection
