Bracelet will not pair
- Make sure the band is charged (place on dock for 5 min).
- Toggle Bluetooth off and on in your phone.
- Force-quit and reopen the Wellex app.
- If still failing, hold the clasp button for 10 seconds — this hard-resets the band.
No score this morning
A score requires at least 4 hours of detected sleep. If you took the band off overnight or the battery died, you will see a calibration card instead of a score. This is expected.
HRV looks wrong
HRV bounces day-to-day. Look at the 7-day trend, not a single night. If a single number is dramatically off, check the band is snug — a loose band gives noisy PPG.
Sync stuck
Settings → Bracelet → Force sync. If that fails, restart the phone. The band has 14 days of on-device buffer, so you will not lose data.
Battery draining fast
Battery life is up to 14 days (~10 days typical normal use), dropping to ~5 days if you trigger a lot of workouts. If you are seeing < 4 days, contact [email protected] for a replacement.
Still stuck
Email [email protected] with your bracelet serial number (Settings → About). Median first response time is 4 hours.
