StepDerby

Turn daily steps into a cheerful cat race with widgets, Apple Watch summaries, and simple challenges for friends and family.

StepDerby makes walking feel like a small friendly race. Pick a cat, start a challenge, and watch your progress move across the track as your real steps update from Apple Health.

Build a daily habit with a race view that is light, playful, and easy to read. StepDerby keeps the focus on challenge progress, cute cats, and simple motivation instead of complicated fitness charts.

Features:

• Cat race progress powered by Apple Health step count
• Daily walking challenges
• Local race history and friendly status updates
• Home Screen widgets for quick progress checks
• Apple Watch app and complications for latest race summaries
• Shared-race invite flow for beta testing small friend groups

Privacy matters. StepDerby does not use ads, does not track you across apps or websites, and does not sell user data. Apple Health step count is used to power the race experience.
