If you don’t want an Oura Ring, you should get yourself the Ultrahuman Ring Air. It is by far the runner-up in the smart ring race — and that’s no insult. Plus, it’s consistently one of the top products ZDNET readers buy month after month; it even earned the number one spot in June, thank you very much. As I wrote in my review of the Ultrahuman Ring Air, “If the Oura Ring is the girl next door, the Ultrahuman Ring Air is the Silicon Valley-based, Bitcoin-mining neighbor who drinks Soylent.” This is the ring for fitness obsessives. The ring monitors all the good stuff: activity, sleep, and recovery. Plus, it prioritizes comfort and a sleek build that doesn’t tarnish quickly or interfere with the rote tasks of your day, like carrying heavy bags, washing hands and dishes, and showering. What’s remarkable about the Ultrahuman Ring Air is the notifications you get during or after your activity. For example, I went on a run with this ring one morning, and after my workout, it notified me to delay any caffeine for around an hour to allow the adenosine I built up from my run to flush out of my system. Later in the day, it reminded me to stretch my legs to recover from my morning run and relieve tension. Review: Ultrahuman Ring AirYou can also document your diet, while the ring’s app offers AI insights into the health information behind each food you eat. Some of the data becomes excessive, but I can imagine that anyone who is all-in on optimizing their lifestyle for marathon training or some other fitness goal will find the information Ultrahuman offers useful. Plus, the app has a Discover tab with guided workouts for everything from pilates, high-intensity interval training, vinyasa yoga, and more. You can sync other workout app data, like the run you recorded on Strava, to the Ultrahuman app, which helps keep all your various activities in one place. The battery life is on par with Oura’s, as I charged both simultaneously and found that they ran out of juice within hours of each other (about six days). And unlike the Oura Ring, which seemingly scratches when in contact with abrasive material, the Ultrahuman has maintained its sheen sans scratches. I don’t have trouble recommending this ring to health-minded individuals honing their workout and recovery regimen. Plus, unlike Oura, the Ultrahuman Ring Air doesn’t come with the price of a monthly subscription. Redditors say the Ultrahuman Ring Air is on par with Oura, but the rings aren’t as effective at fitness tracking as a smartwatch or chest strap. The care and drive for improvement with this ring is palpable: Upon reading user reviews on Reddit, I’ve noticed that Ultrahuman’s founder, Mohit Kumar, is on these threads interacting with users who leave reviews or ask questions about the product — not something I’ve seen before.
