How to Set Up Ideal Data Sources
Follow this guide to setup your Bevel Data Source and Calculation Settings for specific integrations or combinations of devices.
Data Sources can be accessed through your Profile icon → Data Sources.
Calculations can be accessed through your Profile icon → Customization → Calculations.
Apple Watch Only
Calculations (Recommended)
HRV method: Bevel (RMSSD) + Entire sleep
RHR method: Bevel + Entire sleep
Temperature method: Wrist
Use SpO₂ from: Entire sleep
Use RR from: Entire sleep
Calories display: Active or Total energy
Data Sources
Ensure Apple Watch is listed as a Data Source in each category
Hide Data Sources that are no longer in use or that may cause duplicates.
Garmin, Oura, and Google Health
Calculations
These only apply to data coming from Apple Health, so you do not need to adjust them for direct integrations.
Data Sources (Recommended)
During integration, you will be prompted to hide duplicate Data Sources for Garmin or Oura that currently exist in Apple Health.
Ensure Garmin or Oura is the primary source for all data.
Hide any other sources that may cause duplicates (e.g. Strava duplicate of a Garmin workout).
Apple Watch and Fitbit
If you wear both an Apple Watch and a Fitbit, you can benefit from the strengths of each device by configuring your Data Sources correctly to avoid duplicate or inconsistent data.
Calculations (Recommended)
If your Apple Watch is your primary device, use the recommended Apple Watch calculation settings:
HRV method: Bevel (RMSSD) + Entire sleep
RHR method: Bevel + Entire sleep
Temperature method: Wrist
Use SpO₂ from: Entire sleep
Use RR from: Entire sleep
Calories display: Active or Total energy
Data Sources (Recommended)
Active Energy & Resting Energy: Choose one source only (Apple Watch or Fitbit).
Heart Rate: Keep both Apple Watch and Fitbit enabled. Fitbit's continuous heart rate measurements complement the Apple Watch's periodic readings.
Heart Rate Variability (HRV): Apple Watch is recommended. You may leave Fitbit enabled if you want its overnight HRV data. If both are enabled, Bevel averages the available samples.
Resting Heart Rate: Choose one source only.
Sleep: Choose one source only.
Steps: Choose one source only.
Workouts: Apple Watch is recommended for most users. If you prefer Fitbit's automatically detected workouts, use Fitbit instead.
All other metrics: Compare the data from each device and hide duplicate sources where appropriate.
The goal is to use one source for calculated metrics (such as calories, steps, sleep, resting heart rate, and workouts) while using both sources only where they complement each other, such as heart rate (and optionally HRV). This provides the most accurate and consistent data in Bevel.
Other Devices that Write to Apple Health (e.g. Amazfit Helio Strap)
Calculations
HRV method: Apple Health + Entire day
RHR method: Apple Health + Entire day
Temperature method: Body
Use SpO₂ from: Entire day
Use RR from: Entire day
Calories display: Active or Total energy
Data Sources
Hide any other sources that may cause duplicates.
Any Mix of Integrations or Sources in Apple Health
Calculations
Follow setup depending on the primary device you are using.
Data Sources
If you are wearing an Oura ring during sleep and Apple Watch during the day, for example, you will need to choose a main Data Source for certain metrics. For example, you will get Resting and Active Energy from both devices, so hide the device you do not want data displayed from.
Following these steps will ensure that your data is coming from a primary device and that duplicates are carefully handled.
