The problem
Your Watch is a remarkable sensor — it captures your sleep and activity in rich detail. But capturing data isn't coaching. It doesn't plan your sleep, plan your workouts, or track your nutrition. And it treats each signal in isolation, when they're deeply connected.
How you slept shapes how you should train. What you eat shapes how you'll sleep.
Chronotype adds the missing layer — planning and tracking across sleep, activity, and nutrition — reading every signal together to coach you the way the pieces actually work: as one system.
How it works
Early morning
The moment you open the app, Chronotype has already read last night's sleep — duration, stages, accumulated debt — and tells you what kind of day your body is actually ready for. Not a 7am push notification. A read on you.
Morning
Your coach turns last night into a plan for the day — whether to push, hold back, or keep it easy. Training guidance is anchored to how recovered you actually are, not a fixed schedule that ignores the night you had.
Afternoon
Through the day, your coach watches activity, step progress, and your energy battery. It surfaces the right nudge at the right moment — not because a timer fired, but because your data said it was time. Talk to it by voice, hands-free.
Wind down
As your bedtime window approaches, Chronotype shifts into wind-down mode. It knows your target sleep time, your current debt, and exactly what tonight needs to close the gap — dim the room, screens away, bed by a specific time.
Sleep well
Right before sleep, the coaching goes quiet and reassuring — a brief, calm note on where tonight's recovery stands and one thing to do. Phone face down. Consistency is what compounds good sleep over time.
Three pillars, one coach
Chronotype sets your nightly sleep target, tracks your debt against it, and reads stages, HRV, and resting heart rate into a daily readiness picture. That readiness is what drives how hard you should train the next day.
Chronotype builds your daily movement plan, sets goals, and tracks every session from your Watch. The plan adapts to how you slept and how recovered you actually are — a hard night means an easier day, not a fixed schedule.
Chronotype tracks what you eat — logged by photo, barcode, or text, no Watch required. Every meal feeds back into your coaching, because what you eat and when you eat it shapes how well you'll sleep tonight.
The layer above
Sleep, activity, and nutrition don't just affect each other day to day — together they set the rhythm your whole body runs on. Chronotype rolls all three into a single rhythm score, then watches the one thing no individual metric captures: consistency. Going to bed and waking at steady times, day after day, is what compounds into lasting health. Rhythm is the number that tells you whether it's working.
