Numa

Numa is a discreet ear-based health monitoring system for people living with sickle cell disease. Because existing tools are less accurate on darker skin tones, patients often have their pain doubted in clinical settings. Numa tracks oxygen saturation, heart rate, and temperature from the ear and presents that data through a companion app, turning invisible pain into shareable clinical evidence. Available in shades inspired by Fenty Beauty’s inclusive range, the ear cuff is designed to sit discreetly against every skin tone.​​​​​​​​​​​​​​​
