A daily readiness score
Sulis learns your own baselines from HRV, resting heart rate, sleep, respiratory rate, and wrist temperature, then scores your readiness for the day — time‑of‑day aware, never one‑size‑fits‑all.
Sulis quietly unifies your supplements, Apple Health, workouts, recovery, and bloodwork — then writes a plain‑language daily read so you actually know how you are. No rings to close. No guilt. Just clarity.

“Your HRV runs 12% higher on nights you take magnesium and sleep past seven hours. I’d keep that evening dose.”
— Sulis, after noticing a pattern across six weeks of your own data
You’re arriving at today well rested. Sleep ran 7 h 42 m with a long stretch of deep sleep, and your HRV sits 9% above its thirty‑day baseline — resting heart rate eased another beat overnight. Tuesday’s tempo run has been fully absorbed; if you were waiting for a day to push, this is it.
One small note: it’s been three days since your last magnesium dose, and your best sleep this month has followed the evenings you take it. Worth restarting tonight. Your vitamin D refill comes due Friday, and the ferritin trend from last month’s bloodwork is still moving the right way — nothing to do there but carry on.
Six quiet capabilities, all feeding one plain‑language read each morning.
