Best Smart Ring For Android Users
Samsung Galaxy Ring
Pros
- Excellent app
- Super lightweight
- Great integration with android phones
Cons
- More expensive than other options
The Men’s Health crew has got an early look at the Samsung Galaxy Ring ahead of it’s release, and have already been wearing it for a few months. Right off the bat we were impressed by the comfort of the ring, as well as the great aesthetic, with a concave band and stylish notch.
The battery life is impressive, and the square battery case it comes with that contains around three charges is one of its more innovative features. No surprise, coming from a large technology company like Samsung, all of the data and tracking is top rate. This is a great pick for any android users looking to start their smart ring journeys.

Best Smart Ring Under $150
Go2sleep 3
Pros
- Wallet-friendly price point
- Good entry device for those new to smart rings
- Sensor fits inside the hand to help limit shifting during sleep
- Long battery life
Cons
- Bulky sensor design can sometimes move too much and throw off results
For those looking purely for sleep tracking, the Go2Sleep is a budget-friendly device you can comfortably slide on your finger. The big sensor on the end actually faces into your palm, so if you curl your hand up it will theoretically fit into that natural pocket. This updated version of the Go2sleep and its app brings heart rate monitoring, blood oxygen readings, and non-invasive blood glucose evaluation to the table.
One detail we should mention is smart rings rely on how the sensors fit to your body, so the silicone makeup and unique fit of the Go2sleep 3 could shift around during the night and mess up your data. Nonetheless, we still find this device to be a good sleep-tracking alternative for those who don’t prefer smartwatches or sleep-tracking pads.
| Battery Life | Up to 3 days |
|---|---|
| Weight | 6 grams |
| Water Resistance | IPX67 rating |

Ultrahuman Ring AIR
Pros
- No subscription required
- Comfortable fit
- Great sleep tracking
Cons
- Not best at tracking workouts
First impressions, we like the understated design that comes from Ultrahuman. The ring is both light and comfortable to wear, which is always nice. The fact that you don’t require a subscription service, like other smart ring offerings, to use is another plus that comes with the Ring AIR.
As for negatives, the battery life is not as great as other options and it takes awhile to charge. For those looking to use their smart rings to track their workouts, other apps are more accurate.

Most Comfortable
Wellue O2ring Wearable Pulse Oximeter
Pros
- Easy-to-read display
- Works well at purely delivering stats on spO2 and heart rate
- Vibration alert for notifications
- High level of comfort thanks to strap and material
Another wallet-friendly smart ring option, this device from Wellue features a generous screen on top to read your heart rate, blood oxygen level, and time. This smart ring is a purist in the sense it measures heart rate and blood oxygen quite well. It’s also easy to read and interpret, and is comfortable on the finger. The downsides are the limited features in what the ring can measure and the bulky design—which can shift around while sleeping or moving around during the day.

How Do Smart Rings Compare to Smart Watches?/
There are countless products at the intersection of health and technology flooding the market with claims of new, smarter, and better products than their predecessor. And let’s be real, newer isn’t always better. When it comes to wearable devices, that may not be the case. Because of the vast concentration of blood supply in our fingers (each finger has two arteries that run along both sides), smart rings are designed with more sensitivity compared to the average smartwatch.
Another important consideration is wearability and comfort. Some may find it easier to wear a smaller, more inconspicuous device such as a ring more often, which allows for more consistent data collection. And when it comes to tracking biometrics, it’s important to remember the more continuously you are able to wear these smart devices, the more benefit and accuracy you may gain from them.
