Frequently asked questions

The band will not connect

Data is missing or out of date

Why do energy and recovery change during the day

Recovery is calculated from night-time data: heart rate variability, resting heart rate and sleep quality. If your band uploads night measurements later in the morning or afternoon, the value is recalculated — this is expected.

Notifications do not arrive

Check that notifications are allowed in your phone settings and that Do Not Disturb or battery saving is not blocking the app.
