There\u2019s always a certain degree of vaporware at CES<\/a>. It comes with the territory \u2014 especially when we\u2019re talking about ambitious health tech that requires regulatory clearance. So it was really neat that after two years, I got to actually hold Movano\u2019s Evie smart ring<\/a> in my hands ahead of the first wave of units shipping out to customers later this month.<\/p>\n<\/div>\n The Evie Ring\u2019s approach to health tracking has a twist. With wearables, women often feel like an afterthought in design. Just look at smartwatches. Usually, companies prioritize bigger sizes to extend battery life at the expense of those with smaller wrists. The Evie Ring, however, is one of the few woman-first wearables, and that clearly shows up in the design.<\/p>\n<\/div>\n Holding the ring in hand, you can see it has an open gap that slightly flexes to account for finger swelling \u2014 something that can happen in warmer temperatures or as a result of hormonal changes. From an engineering standpoint, that\u2019s actually pretty impressive given the number of sensors and flexible batteries that you need to stuff into such a tiny form factor. <\/p>\n<\/div>\n I also dig that it has an actual case, kind of like earbuds. The Oura Ring comes with a small charging stand, and my cats have knocked it \u2014 and therefore the ring \u2014 off my nightstand and under my bed one too many times. Movano says that the ring itself has an estimated battery life of roughly four days, and that the case itself holds up to 10 full charges. <\/p>\n<\/div>\n Meanwhile, the companion app also includes period tracking and mood logging, which will eventually power AI-based insights based on correlations between menstrual health, hormones, energy, sleep, and activity.<\/p>\n<\/div>\n Stacy Salvi, Movano Health\u2019s vice president of product and strategy, says the company\u2019s built an AI framework that will allow it to pull insights from different types of data. \u201cSo if a woman experiences more restless sleep during the luteal phase per cycle, we\u2019re going to point that out. Some people actually experience better sleep during their cycle and so we\u2019d point that, too. We have actually have different insights on each of those.\u201d <\/p>\n<\/div>\n Since Movano is a smaller company, those types of insights will at first rely on users logging moods. Once enough of a database is built up, then those AI insights will come a lot more naturally with time, Salvi says. Other planned features include a health report that can be shared with doctors, automatic activity detection for workouts, and Android support in the second quarter of the year. (At first, the Evie Ring will be iOS only.) <\/p>\n<\/div>\n At launch, the ring will be able to do both spot checks and passive overnight readings for SpO2, or blood oxygen. That\u2019s fairly standard for wearables these days, but the more compelling thing to me is that Movano has made it a point to use medical-grade sensors, build the device at a medical device manufacturing facility, and seek FDA clearance for its pulse oximeter. <\/p>\n<\/div>\n
