What it tracks
Your body, decoded
Understand your nights
Track deep, light, and REM sleep phases. Wake up knowing exactly how restorative your night was — and what to change tomorrow.
What it tracks→Heart rate variability
Continuous HRV monitoring reveals your autonomic nervous system balance. Higher HRV means better stress resilience and recovery capacity.
What it tracks→Glucose trends
Understand how meals, sleep, and stress impact your blood sugar patterns. Spot spikes, crashes, and build better habits over time.
What it tracks→Cycle tracking
Skin temperature trends reveal cycle phases automatically. Predict your period, understand hormonal patterns, and adapt your routine.
What it tracks→Activity & recovery
Steps, calories, and active minutes — without the bulk of a smartwatch. Know when to push harder and when to rest.
