Design #
As far as the design goes for a smart ring, both these variants are largely identical. The difference the Galaxy Ring bears is the slightly concave curve on the band, which makes it visibly slimmer.
I don’t know if it is a placebo or if the concave design of the Galaxy Ring actually makes it seem slimmer, even though the specs define otherwise.
That being said, neither of the two is highly noticeable except for the initial couple of days of having them on my finger. Especially at night, for someone who hates wearing a smartwatch to measure my sleep, both these rings have been seriously comfortable.
Battery #
The battery life of a health-tracking device is a key factor that influences my choice. Similar in battery life, the Ultrahuman AIR, while it promises 6-7 days of battery life, lasts me a good 5 days before needing a juice up.
The Galaxy Ring lasts me a good 6 whole days, needing a quick top-up at the end of day 6. Both the rings are quite close to what they advertise, so I don’t have any complaints.

Sleep Tracking#


Sleep tracking is one of the major reasons people buy a smart ring in the first place. So if the brands don’t nail this part of the ring, there’s not much left to attract your audience with. Ultrahuman, having the edge by being in the market for fairly longer than the Galaxy Ring, has a proven track record.
The sleep tracking on Ultrahuman isn’t the gold standard for me just yet because, a couple of times, it has failed to log my sleep if I wake up in the middle of the night. Apart from that, the data pertaining to my total sleep and time of sleep and awake time are pretty on point.
The Galaxy Ring, on the other hand, is pretty off when it comes to my sleep tracking. The total time of sleep, especially logging naps and sleep when I’m fully awake, is often the reason I don’t trust this device just yet.
However, the Galaxy Ring, being Samsung’s first stride into a wearable that is totally focused on sleep and general health tracking, there’s bound to be a lack of accuracy. I’m hoping their competition and feedback will push them to make it better with their upcoming updates.
Health Monitoring and Stress Tracking#


Both the Samsung Galaxy Ring and the Ultrahuman Ring AIR measure fairly similar metrics in terms of health tracking, such as heart rate, heart rate variability, blood oxygen, temperature, etc.
With a few features that are exclusive to each, the Ultrahuman AIR with AFib detection and the Galaxy Ring with high/low heart rate alerts, the Ultrahuman still stands out if we compare the accuracy of the two.
The heart rate measurements on the UH AIR, though not the best, are still far better than what the Galaxy Ring measures. The stress tracking on both devices was similar, with none being accurate to how I felt.
This is owed to the form factor of the ring, I believe, wherein the movement of hands, especially while at work, is more, which the ring relates to higher activity and, therefore, more stress.
Activity Tracking#


While smart rings aren’t my go-to for workout tracking, the Ultrahuman AIR is significantly better at monitoring these metrics. The Ring AIR didn’t initially have automatic workout detection, but it was later introduced via a software update.
The Galaxy Ring was launched with automatic activity detection; however, it was only for two activities– running and walking. So basically, the Galaxy Ring does what even my phone can, counting steps. This is quite limiting to its abilities. I’m hoping Samsung, too, rolls out a new one in its upcoming updates.
Galaxy Ring is focused on an audience that prioritizes sleep and wellness, while Ultrahuman, with its Ring AIR, has taken a more holistic approach by incorporating activity tracking along with logging calories.
Yes, you heard that right. By connecting Ultrahuman with MyFitnessPal, logging macros and training simultaneously becomes a dream for any fitness enthusiast.
Final Verdict#
If you’re an iPhone user, your choice between these two rings is already set. The Samsung Galaxy Ring cannot be paired with iOS, which is a disappointment. But since they’re a new entrant and not yet seasoned in the market, this is also reflected in the performance of the ring.
I’m hoping this will be addressed after massive updates to the Galaxy Ring or maybe even the second or third generation of the product. For now, the Galaxy Ring is not living up to the hype for me. As much as I wanted to love it, the Ultrahuman AIR is a clear winner in my books.
FAQs#
01Does the Samsung ring require a subscription?
The Samsung Galaxy Ring does not require any additional subscription.
02Does the Ultrahuman Ring AIR require a subscription?
The Ultrhuman Ring AIR is a subscription-free model, with a few of its PowerPlug features that require an additional subscription.
03Which has a better battery life, the Samsung Galaxy Ring or the Ultrahuman Ring AIR?
The Samsung Galaxy Ring has a slightly better battery life (up to 7 days) in comparison to the Ultrahuman Ring AIR (up to 6 days), with only exceeding by a day. The battery life highly depends on the size of the ring you choose and the features you use on a daily basis. Overall, it didn’t make much of a difference to me.
