Common questions.
What is a health score?
A health score is a 0–100 value that measures a specific dimension of health — like activity, sleep, or mental wellbeing — synthesized from data collected passively from a user’s phone or wearable. Each score breaks down into contributing factors that explain what drove the result.
Which health scores does Sahha offer?
Five: Activity, Sleep, Readiness, Wellbeing, and Mental Wellbeing — each a 0–100 score with its own contributing factors. They share one integration, so adding a score is a config change, not new plumbing.
Do health scores require a wearable device?
No. Every score works from smartphone data alone via Apple HealthKit and Google Health Connect. Some scores gain extra factors when a wearable is connected, but none require one — Activity and Mental Wellbeing have 100% factor coverage from the phone.
How are scores different from biomarkers?
Biomarkers are raw data points — step count, heart rate, sleep duration. Scores are higher-level measures synthesized from multiple biomarkers. Biomarkers answer “how many steps today?”; scores answer “how healthy is this person’s activity overall, and why?”
How often do scores update?
Scores recalculate in real time — within a minute of new data arriving — and generate retroactively for the 30 days before a user connects, so there is no cold-start gap.
Are scores a medical diagnosis?
No. Scores measure daily wellness patterns; they don’t diagnose conditions or replace medical assessment. They make everyday behavioral patterns visible and actionable.
What does it cost to start?
The Sandbox tier is free for 30 days with every product unlocked and up to 25 development users — enough to wire up scores and build the features on this page before you talk pricing.
