Pleasanton, Calif.-based Movano Health plans to file for FDA clearance of its Evie device — a smart ring for women that tracks oxygen saturation, heart and respiration rates, skin temperature, ovulation, menstrual symptoms, activity, calories burned, sleep and mood.

The company’s filing follows a clinical trial that demonstrated the wearable device’s accuracy in measuring oxygen deficiency and heart rate

The ring, which is made of polished aluminum, delivers results to a mobile app.

The device will offer women medical grade measurements “so they can better understand the ‘why’ behind what they're feeling,” the company said.
