Passive wrist wear
An upcoming wrist device that uses 10 biosensors to capture 130+ biomarkers across cardiovascular, thermoregulatory, electrodermal and autonomic domains, then fuses them with machine learning trained on clinical hormone ground truths to continuously infer estrogen, progesterone, LH and FSH — promising to resolve nine cycle sub-phases.
What it measures
Inferred absolute levels of estrogen, progesterone, luteinizing hormone and follicle-stimulating hormone, derived non-invasively from a 10-sensor, 130+-metric physiological array.
Regulatory status
Pre-launch; peer-reviewed validation pending via Stanford Gladstone BeeHive clinical trials. $11.6M funded; launch targeted Nov 2026.
Validation & accuracy
Inference approach is novel and unproven until the planned clinical trials report; directly measuring large hormone molecules optically is impossible, so accuracy hinges on the ML models.
Data control & export
Data model not yet public; modern-app positioning suggests good UX, but export/API terms are unannounced.
Wearability & battery
A passive wrist wearable intended for continuous wear, capturing signals without user action.
Cost & access
Not yet on sale; pricing unannounced ($11.6M raised).
Who it serves
People navigating perimenopause, PCOS, fertility or training who want continuous hormone context instead of episodic blood/urine tests.
Who is left out or burdened
Unproven until trials report; not yet purchasable; data terms unknown.
✓ Strengths
- Continuous, non-invasive hormone inference
- 10 sensors / 130+ biomarkers
- Targets perimenopause, PCOS, fertility
- Planned clinical validation
✕ Weaknesses
- Pre-launch and unvalidated
- Inference vs direct measurement risk
- Data/API terms unannounced
- Not yet purchasable
35
Why this clinical score. A genuinely novel attempt at continuous hormone inference, but pre-launch and unvalidated keeps the clinical score low until trials report.
45
Why this empowerment score. Promising modern app, yet with export/API terms unannounced and the product unreleased, empowerment is provisional and mid.
55
Why this everyday score. Passive continuous wrist wear with a rich metric set would be highly livable if it ships as described.
Latest news
Reviews & coverage
Coverage is excited about the prospect of continuous, non-invasive hormone inference for perimenopause, PCOS and fertility, while stressing it is pre-launch and unproven pending Stanford-linked trials. The core question reviewers raise is whether ML inference can reliably stand in for direct hormone measurement.
