Ultrahuman Ring AIR
For anyone who’s followed my content on YouTube, you’ve probably noticed me wearing a fitness tracking ring for the past several months called the Ultrahuman Ring AIR.
I’ve had this tracker for about 3 months now, and while I was initially skeptical about how useful a tracker this small would be, I’ve been impressed so far with the results.
Ring AIR: First Impressions
Before we delve into the technical monitoring of this tracker, let’s talk about my overall experience with the Ring AIR.
I chose to wear it on my middle finger, where it wouldn’t get in the way as much, and I found because it’s so small and light that after a few weeks, I can hardly even tell I’m wearing this ring.
Ring vs Watch
I’ve always been interested in tracking my activity, but I have a hard time wearing watches. I’ve tried several styles, small fitness trackers, larger full-featured watch trackers, and while I love the features on these, I sometimes have a hard time wearing them.
Watches tend to be uncomfortable, so it’s much easier to take them off, and it’s much more difficult to sleep with them on.
For me, rings are the perfect balance between good exercise tracking as well as overall activity monitoring.
The Ring AIR also excels with sleep tracking, an added benefit that I enjoy.
Ultrahuman Ring AIR Specs
The ring is extremely small and lightweight, so you can wear it all day without even noticing. With the addition of the long battery life, you can even wear it while you sleep, letting you monitor your activity for the entire day.
Sizing
When it comes to sizing, the Ring AIR comes in custom sizes. While I’m unsure of the size I received, Ultrahuman sends out a sizer box with a full range of plastic rings in the exact same size as the actual ring, including the little sensor bump-out, so you know you’re getting a good fit before purchase.
Colors
The Ring AIR comes in 5 color options. I decided on the matte grey/silver solar called Raw Titanium. It looks good, and it’s not too shiny, so it doesn’t show scratches as much as polished colors.
When you take a look at a close-up of the ring, you can notice that it’s held up extremely well over the three months I’ve had it.
It shows some normal signs of wear and tear, but considering that I’ve worn it almost constantly and it’s taken a pretty good beating, this is to be expected.
Weight
The weight of the Ring AIR is the most impressive aspect for me.
It feels like it weighs virtually nothing, and doesn’t even register on my scale, coming out to a minuscule 2.4 grams, which is barely noticeable when you wear it.
Ultrahuman Ring AIR Battery
The final spec we will cover is the battery life. Nothing would be worse than having to charge a tracker every day, and luckily, the Ring AIR lasts as long as advertised, which is about 6 days on a full charge, allowing you to wear it 24/7 almost all week without charging.
It takes a few hours to fully charge the ring from zero, but instead of taking it off for that long once a week, I found it’s easier to throw it on the charger for 20-30 minutes every couple of days, to keep it consistently almost fully charged.
Active Scenarios
Now that we’ve covered the specs, let’s talk about some of the activity tracking features on the Ring AIR, how I’ve been using it, and the best use case scenario for a tracking ring compared to a fitness tracking watch.
Data Tracking
The Ring AIR collects a surprisingly large amount of data on your daily activity, considering the electronic components are so ridiculously small.
The main data the ring is tracking are sleep, heart rate variability, movement, and body temperature. The ring uses this data to develop some nice health metrics for daily movement, daily stress levels and rhythm, sleep scores, and the amount of time in different sleep cycles.
Sleep Score
Let’s start with sleep. Sleep is one of the most useful features for a device designed to be worn 24/7. By tracking your heart rate, movement, and body temperature, the Ring AIR tracks your sleep. This includes overall sleep, time in bed, and even your sleep stages—how much time you were in REM, light, and deep sleep stages, and more.
It shows you this in a summary on the top and individual breakdowns of each category for every day. It features a graph of your sleep pattern throughout the night, your minimum heart rate, and heart rate visibility.
You don’t need to do anything with this data each morning, but I think the power in tracking consistently over time is that you can notice trends.
For example, it gives you a score for several factors affecting the quality of your sleep, such as efficiency, the ability to get to sleep quickly, consistency, and how well your sleep matches your circadian rhythm.
So over time, you’re able to tell where you’re doing good, and where you may be lacking, which affects a good night’s sleep
If you have consistently low sleep efficiency, you know you need to focus on lowering your activity levels before bed and getting into a more relaxed state before you go to sleep.
Movement Tracking
The next critical statistic the Ring AIR tracks is movement. Like a lot of trackers, it tracks steps, the number of minutes of activity during the day, estimates your calories, and tracks workouts.
It has a function similar to Apple Watch, where you can set goals and track your progress across multiple categories.
The step tracker in particular is interesting to me, since that’s one of the biggest metrics of movement I like to track.
To test the Ring AIR tracker, I compared it to larger fitness tracking watches, including an Apple Watch and my TicWatch. The Ring AIR does a good job of tracking activity and movement, however, I was consistently getting lower step estimates than with fitness watches.
For example, I tracked movement on both devices on a day when I went on a 3-mile walk—Ring AIR caught the movement, but the step estimate was just under 10,000 steps for the day, while the TicWatch and Apple Watch were both closer to 15,000.
Stress Rhythm
The final tracking category I’ll mention is stress rhythm, which I think is a good metric to track that can be useful for long-term health monitoring.
Similar to sleep tracking, it monitors your heart rate and activity levels, compares them to your daily circadian rhythm, and tracks stress levels in several categories, including stressed, stimulated, relaxed, and active.
I think this is interesting because it lets you track long-term trends in your stress levels corresponding to certain times of day.
For example, a high amount of high-stress levels at a time of day when you should be more relaxed can indicate you need to do a better job cutting caffeine or relaxing in the evening, which can help you transition to better sleep.
Best Uses: Ultrahuman Ring AIR
Overall, I’ve been very impressed with the Ring AIR so far. It’s incredibly small, lightweight, and tracks a surprisingly large amount of data for a tiny device with an almost week-long battery life.
My favorite feature on the Ring AIR is sleep monitoring, which has a huge advantage for me over a fitness watch because it’s much, much easier to wear the ring virtually 24 hours a day, especially during sleep.
The movement scores are helpful for overall activity monitoring. It does a good job tracking movement; however, from my research, the step estimates are low compared to other fitness watches.
For me, the best use of this ring is if you want more comprehensive 24/7 heart rate, movement, and sleep monitoring, with a device that’s incredibly easy to wear compared to larger, bulkier watches.
