Quick start
From box to first WVI score in under 10 minutes.

1. Unbox
Open the case. Inside you will find the bracelet, a USB-C charging dock and a single getting-started card. There is nothing to assemble.
2. Charge
Place the bracelet on the dock. A soft pulse confirms charging. A full charge takes about 90 minutes and lasts up to 14 days (~10 days typical with daily active wear).
3. Pair
Install the Wellex app from the App Store or Google Play. Open it, choose Pair a new bracelet and bring the band close to your phone. Pairing uses Bluetooth LE and finishes in seconds.
4. Wear
Slide the bracelet onto your non-dominant wrist, snug enough that it does not rotate. The sensors begin baselining immediately.
5. Wait for the first score
Your first WVI appears the morning after you have worn the band through one full sleep cycle. Until then the app shows a calibration indicator.
The first 48 hours are baselining. Treat the score lightly until day three or four — that is when the personalisation engine has enough data to be useful.
