Advancing technology for prevention. Transforming care.
We build digital tools and noninvasive sensing technology that support healthy habits and metabolic health, grounded in more than two decades of research.
Nudge: add a protein to lunch to stay balanced this afternoon.
Two ways we help people stay ahead of their health.
One builds lifelong habits. The other reads what your blood is telling you, without a needle.
Nutu
A science-backed platform that helps members build lifelong habits for weight and metabolic health.
- No calorie counting. Stay in the green zone with your Nutu Score
- Personalized targets with an emphasis on protein
- AI-assisted logging, barcode scanning and wearable sync
- Aligned with the Dietary Guidelines for Americans
Ember
A noninvasive, multi-parameter tracker that measures hemoglobin, oxygen saturation and more, then turns the data into insight you can train on.
Rainbow® Technology. Many wavelengths of light, one sensor.
Our patented multi-wavelength platform measures eight parameters noninvasively, including hemoglobin and its variants. It has been used in hospital monitoring products since 2005. Ember and Nutu are consumer products and are not the hospital monitoring products described here.
- SpO2Oxygen saturation
- PRPulse rate
- PIPerfusion index
- SpHbTotal hemoglobin
- SpOCOxygen content
- SpMetMethemoglobin
- SpCOCarboxyhemoglobin
- PViPleth variability index
Improving healthspan and lifespan by innovating therapeutic care.
Willow Laboratories was founded in 1998 by Joe Kiani, who also founded Masimo and co-invented measure-through-motion pulse oximetry. We began as Masimo Laboratories, a spinoff of Masimo, and were later Cercacor Laboratories. Today we apply that sensing heritage to healthy habits and metabolic health.
