FAQ
Questions, answered.
When can I get the Alliance Ring?
The Alliance Ring is coming soon. Launch dates, pricing and where to order will be announced on this page.
What does the Alliance Ring track?
Heart rate around the clock, blood oxygen (SpO₂), heart rate variability (HRV), stress, sleep stages with a nightly sleep score, skin temperature changes, steps, calories, workouts and menstrual cycle.
Which sports can it track?
Over 100 sports modes, including running, cycling, swimming, hiking, yoga, strength training and tennis, with heart rate, pace and distance for each session.
Does it have GPS?
The ring uses your phone’s GPS to map outdoor runs, walks and rides, so your route, distance and pace are recorded in the app.
Can I swim or shower with it?
Yes. The Alliance Ring is rated 5ATM, water resistant to 50 metres, so swimming, showering, washing your hands and rain are all fine. Remove and rinse the ring after bathing to help prevent skin irritation from soap or residue.
How long does the battery last?
About 5–7 days with typical use, and up to 13 days with lighter use. A full charge takes around 1.5 hours.
How do I charge it?
Open the charging case, slide the ring onto the charging post with its sensors facing the lightning mark, and close the lid. Charging starts by itself. The case charges from any USB-C cable, and one is included in the box.
What comes in the box?
The Alliance Ring, its compact charging case and a USB-C cable. The case is small enough for a pocket or bag, so you can charge on the go.
Which phones does it work with?
iPhone and Android, through the free companion app on the App Store and Google Play. The app is available in several languages.
Can I control my phone with it?
Yes. Gesture control lets you take a photo on your phone with a simple hand gesture, handy for group shots and selfies.
How do I find my size?
Sizes run from US 7 to US 13, an inner diameter of 17.3 mm to 22.2 mm. Measure the inside of a ring that fits the finger you plan to wear it on and choose the closest size. Most people wear it on the index or middle finger.
How heavy is it, and is it comfortable to sleep in?
It weighs around 3.5 g and is only 2.6 mm thin, with a smooth inner shell, so it is comfortable enough to wear all day and all night.
Is the Alliance Ring a medical device?
No. The Alliance Ring is designed for general wellness and fitness. It is not intended to diagnose, treat or prevent any medical condition. Always speak to a doctor about health concerns.
