Stress scores are estimates
Most apps summarize patterns from signals like heart rate, HRV, sleep, activity, and routine. They are useful clues, not a diagnosis.
Stress scores are easier to use when you connect them to sleep, HRV, resting heart rate, readiness, recovery, routine changes, and your own baseline.

Quick rule
Signal plus situation
Most apps summarize patterns from signals like heart rate, HRV, sleep, activity, and routine. They are useful clues, not a diagnosis.
A higher score can look different after poor sleep, hard training, travel, caffeine, alcohol, illness, a deadline, or missing data.
One high reading is less useful than seeing whether stress, sleep, HRV, resting heart rate, and how you feel are moving together.
Consumer stress scores are estimates from device data. If you have severe symptoms, feel unsafe, or have a medical concern, speak with a qualified health professional.
LongevityMate is built around joining stress, sleep, recovery, HRV, resting heart rate, readiness, watch signals, blood work, goals, and Mate follow-up questions.
We post plain-English stress, sleep, recovery, HRV, heart-rate, readiness, wearable, blood-work, and Mate updates without turning one score into the whole plan.
