About kin

Built for circles,
not crowds.

kin was built for people who want more than a tracker. Small-circle accountability for movement — grounded in presence, not performance.

Circles, not crowds

Small groups of people who keep each other moving.

kin is designed for 2–5 person circles. 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.
