[ 01 ] WHAT NAOMI IS

A smart backing for the earrings you already wear.

Naomi replaces the clasp behind your earlobe. A small light sensor reads your heart rate, HRV, blood oxygen and sleep from the lobe, and the app explains them in the context of your cycle.

Sits behind the lobe, out of sight. What people see is your earring.

[ 02 ] WHY WE'RE BUILDING IT

Wearables weren't made with women in mind.

Most trackers sit on a wrist or a finger, look like tech, and were designed around training. Many of the women we spoke to wanted something else: a way to understand their stress, sleep and energy without wearing a gadget.

Your body also changes through the month. A higher resting heart rate in the luteal phase is normal for many women, yet most apps read it the same way every day. We think the cycle should be the context, not an afterthought.

So we put the sensor where nobody looks: behind the earlobe, in the clasp of the earrings you already wear.
