Device data on Centralive
Centralive passively collects research-grade data from wearables, phones and connected devices across four providers. Available metrics depend on the participant’s device model and the study’s configuration — and every export is de-identified.

Garmin
Watches, the Index BPM monitor and Index S1/S2 scales — heart rate, activity, sleep, stress, SpO₂, body composition and blood pressure.
View Garmin data → OuraOura
The Oura Ring (Gen 2 / 3 / 4 / 5) — detailed sleep, readiness, HRV, heart rate, SpO₂, activity, temperature and cycle insights.
View Oura data → WithingsWithings
BPM monitors, scales, ScanWatch, Sleep Analyzer, Thermo and BeamO — blood pressure, ECG/AFib, body composition, sleep, temperature and vitals.
View Withings data → AppleApple
Apple Watch, iPhone and AirPods through Apple SensorKit, in a custom study app: heart rate, ECG, PPG, motion, sleep, wrist temperature, phone use and places.

Compare devices
Line up two or three devices to see which metrics each one captures — Garmin watch tiers against each other, or a Garmin watch against the Withings ScanWatch.
High level shows the broad data types each device captures (the number is how many individual metrics it provides in that group); switch to Detailed for every metric. Garmin watches are grouped by feature tier, so capabilities are indicative — a few metrics (e.g. ECG, SpO₂ or skin temperature) can vary by exact model, firmware and region. Rows where the devices differ are highlighted.
How exports work
Exported data is grouped by device class, then by category, then by participant. Every data file shares the same leading columns — participant ID, local timestamp, timezone and UTC timestamp — followed by the metric values and the device model. Free-text and account identifiers are dropped at ingestion, so exports stay de-identified.
