The problem

The bottleneck inwearable healthisn't hardware.It's the algorithm layer.

Your heart rate works in the lab. In the field it lags during a sprint, drifts during typing, and disagrees with itself on the same wrist five minutes later.

Solutions

Insights, ready for production.

Heart, sleep, activity, breathing, and women’s health. Validated, confidence-scored, real-time. Drop the one your device needs in today, add the others when you’re ready.

Kit 01

Heart Kit

Heart rate that holds at rest, in motion, and through the recovery after. Beat-to-beat extraction from the sensors your device already carries.

01
Beat-to-beat from PPG
Clean RR intervals pulled from a noisy wrist signal. Motion-tolerant where it counts, honest about the moments it cannot reach.
02
Rhythm beyond the bpm
Heart-rate variability that tracks the day, resting heart rate that drifts with fitness, irregular beats that surface for review.
03
Recovery as a signal
How quickly the heart returns to baseline says more than the peak it reached. Captured in every interval and overnight window.

Signal audit

Before you pick a kit, let us look at your signal.

Send us a few hours of raw data from your device. We come back with a short written report on what your signal can support today, what is borderline, and what your firmware would need to change to unlock more.
