[ 01 ] WHY THE EARLOBE
A clearer signal,
closer to the source.
Your earlobe is soft and thin, full of small blood vessels, with little cartilage in the way. For a light sensor, that makes it a far better place to listen than the wrist.

STRONGER PPG SIGNAL QUALITY THAN THE WRIST
SOURCE · UNIVERSITY OF WASHINGTON, PPG EARRING STUDY · WAVEFORMS ARE AN ILLUSTRATION · THE STUDY SHOWS SIGNAL QUALITY, NOT OVERALL ACCURACY · NAOMI'S PROTOTYPE IS STILL BEING TESTED
Numbers alone don't say much. Naomi compares every reading with your own baseline and the phase of your cycle, so a change is explained, not just counted.
HRV
0ms
The variation between beats: a window on recovery and stress.
It tends to climb as estrogen rises, and dip later in the cycle.
Blood oxygen
0%
How well oxygen is carried through your blood.
Read with red and infrared light, the same principle as a clinic's finger clip.
Sleep
0h 0m
How long and how well you recover overnight.
Restless nights before a period are common. Naomi shows the pattern.

[ 03 ] DISCREET BY DESIGN
No screen on your wrist. No band. No ring to explain. Just the earrings you already wear, with something smarter behind them.
Studs, hoops, the pair you never take off. Naomi takes the place of the back on almost any earring with a post, so you keep wearing the jewellery you love.
