Your routines, actually executed.
Design a morning anchor, a workday shutdown, an evening wind-down. Run them daily. Stop re-planning your life on a screen.
Free to use. Works on any phone, any browser.
Quiet. Direct. Out of your way.
One tap to start. A coach voice that knows where you are. No streak guilt, no points economy, no friend feed clutter — just the routine you set up, running.
Greeting, inspiration, and a coach voice that actually knows where you are.
In motion — one step at a time. The app stays out of your way.
Browse routines shared by other people. Clone what works for you.
Proportional scoring. Partial runs count. No streak theatre.
A routine, not a points game.
Routines, not just habits
A habit is a single check-off. A routine is a sequence — a morning, a shutdown, a wind-down. Routine OS runs the sequence, step by step.
A coach that's quiet
No notifications campaign. No bargaining. The voice nudges when it helps and stays out of the way the rest of the time.
History without guilt
Streaks reset gently. Missing a day doesn't erase the year. You see the shape of your week, not a scoreboard punishing imperfection.
Cairn — a small device that lives where your routine does.
A physical companion to the app. Sits on your desk, your bathroom counter, your bedside table. One tap to start the routine that lives in that spot.
