WearSightful Data API
One API for wearable, health and fitness data.
Connect your application to multiple wearable and health data sources without building every integration from scratch. One unified API — not a separate 'wearable' API and 'health' API — spans every data domain your product needs.
Why one API instead of two?
A wearable data API provides software access to data generated by wearable devices, mobile health platforms and connected apps. Splitting that into a separate “wearable API” and “health API” only raises the question: what is the difference? WearSightful uses a single Data API that exposes every data domain — so your team ships product features instead of maintaining provider-specific connectors or reconciling two APIs.
- One integration layer for multiple providers
- Normalized data across every domain below
- Historical data access
- Source and device metadata
- Webhooks and synchronization events
- Designed for scalable B2B applications

}Data domains
One API. Every data domain.
The WearSightful Data API is organized by data domain rather than by source — so your application code does not change as new providers are added.
Activity & Movement
Steps, distance, calories burned and active minutes.
Sleep & Recovery
Sleep stages, sleep duration, efficiency and recovery scores.
Heart & Cardiovascular
Heart rate, resting heart rate, heart rate variability and blood oxygen.
Body Metrics
Body temperature, weight, body composition and respiratory rate.
Exercise & Workouts
Workout sessions, training load, pace and exercise type.
Nutrition & Hydration
Nutrition logs and hydration tracking, where supported by the source.
Lifestyle & Context
Menstrual cycle information, mood and user-entered tags and context.
Data, not diagnosis
Health-related data is not the same as a medical claim.
Some data domains above relate to a person’s health and wellbeing. That does not mean WearSightful provides medical interpretation or makes clinical decisions. The distinction matters:
Data
“Heart rate was 72 BPM.” A normalized measurement WearSightful can provide.
Interpretation
“This person has a cardiovascular condition.” A medical interpretation WearSightful does not make.
Decision
“This person should seek treatment.” A medical decision outside the scope of this platform.
