The ring is waterproof, it never gets hot, it doesn’t have a screen or a vibration motor; as far as smart devices go it’s especially inert. But it has a battery that will last at least seven days, and comes with a funky clear storage box that can store the same amount of power. If you leave this box at home and plugged in you just need to put the ring in for an hour a week, and if you’re going somewhere, you can take the box to get two full weeks without needing a charge.

Initial setup is seamless; you just open the case near your phone and the ring will pair up via Bluetooth. From there, it works just like a smartwatch. Periodically, the ring will send the data it’s collected to the phone, where it’s crunched and integrated with the Samsung Health app. As a platform, I tend to find it a bit less informative than Apple Health or Fitbit, but it is comprehensive and covers all the bases you’d expect.

With the ring on, I get a steps counter, an estimate of my active minutes and an idea for the energy I’ve burned throughout the day. I get notifications to move if I’ve sat still too long, exercise such as running is automatically tracked, and my heart rate, blood oxygen saturation, respiratory rate and “stress” is measured thanks to the sensors and thermometer.

While you sleep, the ring turns its measurements into a map of your movements through light, deep and REM cycles, and scores your sleep out of 100 based on this data plus time slept and consistency. Over the past few weeks, I’ve compared the results from the ring to other watches and trackers, and it tends to be very close.

Samsung Health turns this data into a daily “energy score” that’s supposed to let you know how ready your body is for training. It will also give a quick paragraph of advice, such as ideas for extra activities if you haven’t been hitting your goals.

I think most athletes and people serious about their workouts are going to prefer a watch, for the extra sensors and capabilities such as music playback, workout plans and real-time stat readouts. But if you’re just keeping an eye on your steps, sleep and daily workout, the ring does a great job.

Outside of that, there isn’t much to it. If you lose the ring, its last known location will appear in Samsung Find, and while it can’t vibrate or make noise, you can set it to blink its sensors to make it easier to locate (which I was thankful for at one point when it slipped off while I was doing the laundry). And the ring can detect when you smack the finger it’s on against your thumb or palm twice in a row, to snooze alarms or remotely take a photo, but this currently only works on Samsung phones and not other Androids.

If what you want is a way to collect health metrics without a watch, the Galaxy Ring works, and I really only have two concerns.

First is that it’s very expensive, to the point that you could probably get both a Galaxy Watch FE and a regular titanium ring for less. And since the Galaxy Ring isn’t particularly attractive as a ring, it’s going to be difficult to justify.

The second concern is a bit speculative, but it’s about longevity. The tiny battery in this thing is bound to start giving out within two years, and at some point will become entirely useless. There’s no way to repair it (either if the battery runs out or if it’s somehow crushed, which is not unheard of for rings), so like most earbuds, it’s as disposable as tech can get. Of course, with earbuds, people may be happy to upgrade every few years to get new features or tech, but I’m not sure what can be added to a ring, except maybe a promise that it won’t end up as e-waste in 30 months’ time.
