The agentic system to track and change your life.

One app that tracks your whole life — you just say it, the agent logs it. World-class AI coaches read the data and get you improving, on every device you own.

Track

Easily track everything in one place

Say it once and it's logged — filed into the right collection, structured, charted, streaked. No forms, no five apps, no friction.

You don't need all the other apps

One subscription instead of seven that never talk to each other.

Coach

Talk with world-class AI coaches

Your coaches read every log — training, sleep, meals, money — so their advice is grounded in your actual data. Pick one from the library or build your own from a paragraph of personality.

Coach Adler

Strength & conditioning

Why has my squat stalled?

Volume's fine — recovery isn't. You slept under six hours before four of your last seven sessions, and every failed set follows one. Move Thursday's squats to Friday.

Nova

Nutrition

I train hard. Why is the scale stuck?

Weekdays you average 1 880 kcal, weekends 2 600. Your deficit disappears every Saturday. Keep the pizza night, drop the Friday snacking — that's the entire gap.

Where does my money actually go?

€142 a month across nine subscriptions — three untouched since April. Cancel those and you've covered the gym membership twice over.

You decide what they see, what they say, and when they're allowed to interrupt you.

Visualize

See your whole life in beautiful dashboards

Every log rolls into charts on its own — trends, streaks, totals. Ask the agent for a new chart and it builds one from your data.

Your data lives on your devices

Every device keeps a full copy of your data, so screens open instantly and everything works offline — on a plane, in a basement gym. Sync happens quietly in the background. If our servers go down, you won't notice.
