Health & Wellness Notice

What Mere is, what it isn't, and when to talk to your doctor instead.

Last updated October 9, 2026.

Mere is designed to read your pulse every night and tell you, in plain English, how you seem to be doing. The ring and app aren't available yet, so this notice describes them as designed, and details may change before launch. It explains what those readings are, what they are not, and where Mere stops and your doctor begins.

A wellness product, not for medical use

Mere is designed as a low-risk general wellness product and is not intended for medical use. The ring, the app and everything they show are made to help you notice how you're doing day to day. They are not intended to diagnose, treat, cure or prevent any disease or condition. They are not a substitute for care from a doctor or another qualified professional.

Mere has not been cleared, approved or otherwise authorized by the U.S. Food and Drug Administration (FDA). The FDA describes general wellness products as low-risk products intended only for general wellness use, such as maintaining or encouraging a general state of health or a healthy activity (FDA, 2026).

Readings are estimates, measured against you

Mere spends your first 14 nights learning your normal. After that, each reading is compared with your own baseline, not with a population average. That covers heart rate, HRV, blood oxygen, sleep and the shape of your pulse.

Every number and pattern in Mere is a wellness estimate, not a clinical measurement. Blood oxygen, for example, is not a medical oximeter reading. Optical sensors read best when you're still. In one study of six wearables, heart-rate error was on average 30% higher during activity than at rest (Bent et al., 2020). Even asleep, you move, so any single night can be off. The trend across many nights tells you more than one number.

Biological age and vessel age are estimates

Mere shows your biological age as an estimate with a likely range around it, updated weekly. It is a wellness estimate drawn from your readings, not a medical test. It says nothing about the health of any one organ, and it does not predict how long you will live. Vessel age is an estimate too: a wellness estimate, not a test of your heart or blood vessels. Watch which way they move over months. Don't treat any single week as a verdict.

About the ECG sensor

The ring's shell includes an ECG sensor. Mere is a wellness product: it does not use this sensor, or anything else, to diagnose, detect or rule out any heart condition. Nothing Mere shows is a substitute for an electrocardiogram taken by a clinician. If something feels wrong, don't wait for a reading.

The ring notices. Your doctor decides.

When your readings move away from your normal, Mere may tell you something is worth a look. It won't name a condition or treat a reading as a finding. What a change means is for your doctor to decide. Answers from Ask Mere are wellness information, not medical advice, and they can be wrong.

Please don't start, stop or change a medicine or treatment because of something Mere shows you. And don't put off care because your readings look calm. A quiet night is not an all-clear.

In an emergency

Mere is not an emergency service. If you think you or someone near you is having a medical emergency, call 911 or your local emergency number right away. Don't wait for a reading, a pattern or an answer from Ask Mere. Sharing with your circle is not a way to call for help.

The Formula

The Mere Formula is in development. It will launch after the ring, and it will be optional: the ring will work on its own.

When it arrives, the Formula will be a dietary supplement: two pods a day, built from your nights, your check-ins and any labs you choose to add, and rebuilt every 30 days. It won't be a medicine, and it won't be meant to treat any condition or to replace anything your doctor has prescribed.

Where a vitamin or mineral has a Tolerable Upper Intake Level (UL), we're designing the Formula to stay under it. The UL is the highest average daily intake, usually counting food, water and supplements together, likely to pose no risk of adverse health effects to almost all people in the general population (Institute of Medicine, 1998). Our count will include both pods and the supplements you tell us you take. Food counts toward most limits too, and we won't see everything you eat. Before each box ships, you'll see what changed and why.

Pregnant, nursing or on medication? Ask your doctor first. Some supplements can change how the body absorbs, breaks down or clears a medicine (FDA, 2022). Please don't stop or change a prescribed medicine to make room for the Formula.

These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

Screens and images on this site

The app screens on this site are captures from a prototype. Every value on them is illustrative, not a real person's readings. Some images on this site are illustrations, including the people in them. No one pictured is a Mere member or customer. The ring and the Formula are shown as designed and are still in development, so final details may differ.

Traditional pulse reading

Reading the pulse by touch is one of medicine's oldest practices, found in several ancient traditions (Ghasemzadeh and Zafari, 2011). Mere borrows that patient way of looking: how the pulse rises, peaks and settles, read as a whole and over time.

Mere's nine patterns, from Steady to Sensitive, put traditional ideas into plain English to describe how you seem to be doing. They are a wellness lens, not a medical finding, and they have not been evaluated as medical tests. The free Reading will open to the founding list first and will work the same way: eight questions and an optional tongue photo will suggest a pattern, never a diagnosis. It will come with its own privacy notice and will ask for your consent before you share a photo.
