Your Tuesday 20 October
-
Nutrition Coach set this slot
Steady carbs to start a day with intervals in the evening.
-
Nutrition Coach set this slot
About two hours before tonight's session, with water through the afternoon.
-
Exercise Coach set this session
Six fast 800 m repeats with 400 m easy jogging between. About 50 minutes with warm-up and cool-down.
Nutrition Coach added a note
A snack with about 40 g of carbs around 16:30, and water through the afternoon.
Sleep Coach added a note
A hard session this late keeps your heart rate up for a while. Your bedtime window stays at 22:45 tonight.
-
Sleep Coach set this slot
Lights out between 22:45 and 23:15. Later than usual, because of tonight's intervals.
Week 1 of a 16-week marathon plan, race day Sunday 7 February 2027. The app shows the plan as a day-by-day list today.
There is an AI coach for each hub you use: Sleep, Exercise, Nutrition, Resilience, Longevity and Health Record, plus one for each sport you do. Add a hub for anything else you track and choose its AI coach.
Measured for you, not the average.
A resting heart rate of 54 is normal for most people. If yours has sat between 46 and 50 for six months, 54 tells your AI coaches something.
Your Digital Twin knows the difference. It is a model of you, built only from your own data, and it gets sharper every month you measure.

How it works
-
1Connect what you use
Your wearable syncs on its own. A lab report becomes a list of values that you check before they enter your Health Record, each shown against the range printed on the report.
-
2The Twin learns your normal
Every reading is compared with your own history, not an average. Gaps stay visible: a missing day is never guessed.
-
3Your AI coaches suggest, you decide
A morning brief, food ideas for the evening and a plan to race day that moves when your data does. Nothing changes until you say yes.

What happens to your data
It reads only the sources you connect. Nothing is imported without your authorization, and you can stop a source at any time in your phone's settings.
We use your data only to provide the service to you, not for advertising, not to sell it and not to train general-purpose AI models.
