Wearables
Works with the devices you already own.
Connect your Apple Watch or Garmin directly. Bring your Oura Ring or Whoop through Apple Health or the portal. Fueld reads it all.
First-class integration
Direct connection. Full data. No compromises.
Apple Watch and Garmin connect directly to Fueld with full data access. Everything else connects via Apple Health — simple, private, and always in your control.
Apple Watch
The deepest integration we have. Every data type Apple Watch tracks — including wrist temperature for cycle-aware analysis — flows directly into Fueld.
- HRV, resting heart rate, respiratory rate
- Sleep stages, duration, efficiency
- Wrist temperature (Series 8 & Ultra — cycle-aware)
- Activity, steps, active calories, VO₂ Max
- Nutrition (via Apple Health & Fueld food tracking)
- Menstrual cycle data from Apple Health
Works with all Apple Watch models from Series 4. Cycle-aware features require Apple Watch Series 8 or Ultra for wrist temperature.
Garmin
First-class Garmin integration via the official Garmin Connect API. Body Battery, training load, stress, and all the data Garmin users rely on — in Fueld.
- HRV, resting heart rate
- Sleep stages, Body Battery, respiration
- Stress score and recovery tracking
- Activity, steps, VO₂ Max, training load
- Wrist temperature (compatible models)
Fueld has official Garmin Connect API approval. Data syncs automatically from Garmin Connect — no manual export required.
Oura Ring
Connect your Oura Ring to Apple Health on your iPhone and Fueld picks up HRV, sleep, and readiness data automatically.
- HRV, resting heart rate
- Sleep stages and readiness score
- Activity and steps
- Body temperature (via Apple Health export)
- Menstrual cycle data
Oura Ring 3 and 4 both supported via Apple Health. Enable Oura → Apple Health sync in the Oura app.
Whoop
Whoop users connect via Apple Health. Recovery, strain, and sleep data flows into Fueld alongside your nutrition and other health pillars.
- HRV, resting heart rate
- Sleep performance and stages
- Recovery score
- Activity and strain
Enable Whoop → Apple Health sync in the Whoop app settings. Direct Whoop API integration is on the roadmap.
