What’s your Pattern?

Everybody is different.
Nine patterns, in plain English.

Your free Reading: eight questions and an optional tongue photo, an old way of reading the body. The ring then confirms or changes your pattern, night by night.

Mere app, Free Reading result: your Pattern is Wired, with your place on the founding list.

Patterns are wellness reflections, not diagnoses, drawn from a modern nine-type body constitution framework with roots in traditional wisdom.

The signal

Your watch counts.
Mere reads.

The shape of every pulse at your finger, not just your heart rate.

Research recordings · not a Mere ring

  1. 1RiseHow quickly your heart pushes.
  2. 2PeakHow strongly the wave arrives.
  3. 3NotchWhen a heart valve closes.
  4. 4EchoWhat your vessels send back.

Mere reads all four nightly, against your own normal.

Independent research

Studies show pulse shape carries more than rate. Not Mere results: Elgendi, Current Cardiology Reviews 2012; Abbaspourazad et al., ICLR 2024. Both lines are real ECG and fingertip pulse recordings, taken together from one healthy adult at rest on research equipment, not a Mere ring. Contains information from the Pulse Transit Time PPG Dataset (Mehrgardt et al., PhysioNet 2022), made available under the ODbL v1.0.
