Step competitionswith your friends.
Your iPhone is already counting. Lockstep puts the number on a leaderboard and lets somebody beat you with it.
Free on the App Store. iPhone only — it reads the steps Health already holds.
How it works
01
Sign in, connect Health, pick a username.
Sign in with Apple. Lockstep asks Health for one thing — your daily step total — and never writes back.
02
Start a competition and send the link.
A week, a month, a custom range, a head-to-head, or a race to a step target.
03
Steps sync on their own.
Including overnight. Nobody has to remember to log anything.
04
Leave a note on a day.
Take a rest day and say so.
No ads, no tracking.
No analytics, and nothing sold to anybody.
Step counts, nothing else.
It reads your step count from Health — no routes, no workouts, no heart rate — and never writes back.
No public profiles, no feed.
Only people you compete with see your steps.
