SOMA measures oestradiol, progesterone and cortisol directly from sweat, in real time, and turns your hormonal data into training intelligence built specifically for your physiology. Not a male model with your cycle bolted on. Built from the ground up, for you.
Every major wearable on the market was built and validated on male physiology, then sold to everyone. Your hormonal cycle isn't a variable they account for, it's a gap they've never closed, because you were never who they were designing for.
That's not even remotely a small oversight meaning your recovery scores, readiness scores and training loads you've been trusting were calibrated on a body that isn't yours. SOMA exists because female athletes deserve technology built around their own physiology, not male data with a pink label on it.
We're not adding a "female mode" to an existing product. Every part of SOMA, from what it measures to how it interprets the data, starts with the female athlete.
Female athletes train and compete on protocols built almost entirely on male physiology.
Right now, hormones are treated as noise, not data.
What's your biggest frustration with existing performance tracking tools? Over half mention their cycle, hormones or female physiology.
"I feel like they have no idea what is going on with my body."
"My Garmin doesn't know when I'm on my period so if I end up doing an easier session it doesn't take that into consideration."
"They feel very male centered and don't often take into consideration fluctuations in hormones."SOMA athlete survey, n = 40
Not inference from downstream proxies. Not episodic testing. SOMA reads oestradiol, progesterone and cortisol straight from sweat, continuously, and turns it into a Performance Readiness Index you can train by.
Oestradiol, progesterone and cortisol, measured directly from sweat, alongside HRV and skin temperature. This is the core of the SOMA Watch and the focus of our current research.
As the platform grows, SOMA will expand to include metabolic markers like lactate threshold and glucose, and broader physiological data like SpO2 and sleep architecture. We'll only claim a capability once it's validated.
"We're not asking you to trust a black box. Every claim SOMA makes is backed by published science, or by our own research in progress, and we'll tell you plainly which is which."

Direct molecular measurement from sweat. Not calendar-based estimation, not downstream inference.
Training that finally accounts for the cycle you're already running through.
See the hormonal patterns behind fatigue and setback before they cost you a season.
Credible, direct data on the female athletes you coach. No guesswork, no proxies.
SOMA measures oestradiol, progesterone, and cortisol directly from sweat. It does not infer your cycle phase from calendar dates or symptoms you log by hand. That direct measurement is the whole point of the device.
Those tools work from predicted cycle phase or self reported symptoms. SOMA reads your actual hormone levels through the skin, alongside HRV and skin temperature, so the training guidance is based on what your body is doing right now rather than what a calendar says it should be doing.
Sweat based hormone biosensing has peer reviewed research behind it, and SOMA's own research programme includes a pre registered systematic review of the accuracy of sweat oestradiol and progesterone detection. We are building on real evidence, not marketing claims.
SOMA is currently in the building process. Research is our first priority, and we are working closely with a cohort of female athletes to get the science right before anything goes to market. Join the waitlist below and you will be the first to know as things progress.
Yes. The Coach Portal is being built alongside the watch itself, not added on later. It gives coaches biomarker level visibility across their athletes so training decisions can be based on data rather than guesswork.
All female athletes deserve training built around their own biology, not borrowed from research on men. That belief is at the core of everything we are building.

"Hormones have always been in the data. We just never had a way to read them in the moment. That's the layer I'm building."
