Personal trend estimate · daily imported summariesDaily HRV, resting heart rate, oxygen and respiration are not confirmed overnight measurements.
About your estimate & overnight data
This estimate uses HRV (40%), resting heart rate (25%) and sleep duration (35%). The heart signals use the median of available readings in the previous 28 days, from the same imported source and HRV metric. At the usual heart values, each heart component is 70/100; sleep reaches 100 at 8 hours. It is our own heuristic, with no WHOOP data or algorithm.
HRV: 70 + 100 × ln(today / baseline). Resting heart rate: 70 + 200 × (baseline − today) / baseline. Sleep: 100 × hours / 8. Each component is capped to 0–100.
- HRV: awaiting data · 0 earlier readings
- Resting heart rate: awaiting data · 0 earlier readings
- Sleep duration: awaiting data · 0 earlier readings
Still needed: HRV for this date; Resting heart rate for this date; Sleep duration for this date; 7 earlier HRV readings of the same metric; 7 earlier resting heart rate readings.
Wrist temperature is not connected. Confirmed overnight vitals need a native Apple Health connection with timestamped sleep and vital samples. This web app currently reads imported daily summaries.
