Small by design
Small groups of people who keep each other moving.
kin is designed for circles of up to five. No followers, no leaderboards, no strangers — just the people you already know, showing up at their own pace.
The full experience
Designed to disappear between moments.
Settings that stay tiny. Challenges that invite rather than demand. A home view that quietly reflects your circle’s rhythm — never their rankings.
Presence
Movement shared without performing for anyone.
Privacy
Circles are private by default. No public profiles.
Patience
No streaks, no urgency, no guilt-inducing nudges.
People
People you know, not followers. Names, not numbers.
