Strain Troubleshooting

Check the following:

• You are wearing your device during sleep (for RHR)

• Heart Rate zones are set correctly

• HRV and RHR data are syncing properly

If needed:

• Open Apple Health to trigger a sync

• Clear cache and reload data in Bevel

This can happen if:

• Heart Rate zones are misconfigured

• Heart rate data is incomplete

• Your baseline is still calibrating (first 2–6 weeks)

Review your settings and give the app time to calibrate.

Cardio Load requires:

• Recent workout data

• Consistent heart rate tracking

• At least several weeks of data for accuracy

If it’s missing:

• Check your integrations

• Ensure workouts include heart rate data

If it shows “Calibrating”:

This means there isn’t enough consistent workout data yet. Cardio Load needs regular training to determine your status.

To resolve this, aim for:

• ~3 workouts per week

• Consistent training over at least 2–3 weeks

This helps the algorithm gather enough data to provide an accurate Cardio Load.

Strain requires heart rate data to calculate effort.

If you log a workout but there’s no heart rate data:

• Cardio workouts → No Strain will be generated

• Strength workouts → Strain may still appear if exercises are logged

Strain and Cardio Load rely on accurate and consistent heart rate data.

For these features to work correctly, Bevel needs:

• Reliable Resting Heart Rate (RHR)

• Properly configured Heart Rate zones

• Consistent sleep data (used to establish your baseline)

RHR is typically derived from sleep, so wearing your device overnight is important.

If any of this data is missing or inaccurate, your Strain or Cardio Load may appear incomplete or incorrect.
