Frequently Asked Questions

What types of data does the PhenomeTech Ring track?

The PhenomeTech Ring gives you a complete picture of your health, all from one device on your finger:

Capacity: your daily recovery score
Sleep: hours of sleep and rest quality
Activity: steps, step distance, and calories
Heart Health: heart rate, resting heart rate, heart rate variability, and blood pressure
Respiratory Health: respiratory rate and blood oxygen (SpO₂)

How do I choose the right size for my PhenomeTech ring?

Order our free ring sizer and wear each size at home for a day. Once you've found the snug, comfortable fit that stays secure around the clock, submit your size and check out. A consistent fit is what keeps your readings accurate.

What's the difference between the Titanium and Ceramic PhenomeTech Rings?

They track exactly the same health data: the difference is purely material and style. Both come in a range of colors, so it really comes down to feel. Titanium gives you a durable metal shell, while Ceramic is a little thinner for a sleeker, lighter finish. Pick whichever look you prefer.

Do I need the app or an account?

Yes. Your ring pairs with the Phenome app, where all your health data lives: that's where you'll see your readings, trends, and daily Capacity score. You'll set up a free account to get started.

Does the PhenomeTech Ring need a subscription?

No. There's no subscription and no hidden fees. Once you have the ring, full access to the app and all your health insights is included.

Is my health data private? Who can see it?

Your data is yours, full stop. Phenome Longevity operates in full compliance with UK GDPR, and your account is protected with secure authentication, so only you, and anyone you choose to share it with, can access your information.
