Welcome to LifePrisma

Congratulations, your PrismaRing is here!

Your body already knows. Now you do too. Starting today, the ring follows your sleep, your heart and your recovery, so you can get to know yourself better and take better care of your health.

In the box: the ring, the charging dock and the USB cable.
  1. 1

    Try it on

    Heads up: don't put the ring on the charger before trying it on.Size exchanges only apply to rings that were never activated. Once it's activated, it's yours.

    It arrives asleep. You can wear it on any finger. What matters is that it feels comfortable.

    It slides over the knuckle with a little resistance.
    The sensors face your palm.

    Too big or too small? Don't put it on the charger. Click here to request an exchange.

    Wake the ring

    Fits? Now go ahead: place the ring on the dock and plug the USB cable into a phone charger or a computer.

    The light comes on when it wakes up. Leave it charging until full.

    Get the LifePrisma app

    The ring only talks to the LifePrisma app. That's where you see everything it measures. Sign in to your account or create one.

    Pair the ring

    With the ring close to your phone, in the app:

    1On the Wallet tab, tap Smart Rings.
    2Tap Pair a ring and follow the app.

    The ring doesn't show up in your phone's Bluetooth settings: pair it only through the app.

Easy! You two are just getting to know each other!

The ring takes a few days to understand what your body is like, how you move and how you vary through the day and from one day to the next. That's how it builds your baseline. Don't be surprised if readings don't make much sense in the first 7 days: you're still getting to know each other. Wear it all the time: to sleep, shower and exercise. Take it off only to charge it. The battery lasts 5 to 7 days.
