When it comes to day to day comfort, however, I have found in my personal experience that the two products follow exactly opposite routes. Regarding their physical design in the context of Fitbit Air vs Ultrahuman Air, the first device comes with a modular pill-shaped pod with dimensions of 34.9 x 17 x 8.3 mm which can be easily detached from the strap, whereas the latter one comes with a unibody solid metal ring build that is extremely thin, just 2.4 mm thick. The positive aspect of the Fitbit Air is that this device is lightweight and weighs only 12 grams when attached to the band, while the best thing about the Ultrahuman Air is the phenomenal lightweightness and ranges from only 2.4 to 3.6 grams depending on your ring size. Besides, the Fitbit Air comes with the main body of the tracker made from lightweight polycarbonate recycled materials that will not interfere with long sleeves, while the Ultrahuman Air comes with a high-quality aerospace titanium shell with a tungsten carbide coating.
However, both of these designs have their own disadvantages in terms of actual use. For example, the Fitbit Air provides users with interchangeable woven textile bands which can easily be changed according to personal preferences. In turn, the Ultrahuman Air is provided with non-interchangeable metallic bands with different finishes, such as Aster Black or Space Silver. Personally, I also found wearing a ring a little inconvenient while washing my hands, as I often had to remove it to clean my hands properly. Having to take it off repeatedly can become annoying during the day. You will definitely have to choose which one to get during the purchasing process and then there will be no way back.
You will definitely have to choose which one to get during the purchasing process and then there will be no way back. However, what I really appreciate about the Fitbit Air is that it leaves your fingers free for typing on a laptop or lifting up weights in the gym. The only downside about it is that its textile band becomes extremely wet, cold and uncomfortable after a sweaty exercise.
On the other hand, the Ultrahuman Air is offered in an elegant design where there is nothing on your wrist, making it easy to wear traditional mechanical watches, but the product has a serious design flaw if you do weight lifting, since its titanium cover will make a loud screeching noise when rubbing against metal dumbbells. In addition, the Fitbit Air is provided with a fabric-like touch feeling on the skin which is adjustable by means of a loop, whereas the Ultrahuman Air has a metallic feeling which is not adjustable at all.
Verdict: I believe that the Fitbit Air will suit people who enjoy wearing interchangeable wristbands, along with those who like to have their hands free during vigorous workouts at the gym. On the other hand, the Ultrahuman Air would be best suited to people who like to wear the very light and luxurious titanium band around their wrists.
Health Tracking#
Both the Fitbit Air and Ultrahuman Air can be described to work passively when it comes to monitoring one’s general health. The Fitbit Air is known to offer a full set of sensors in one’s wrist while the Ultrahuman Air provides finger-mounted blood pulse sensors that are very sensitive.
Sleep Tracking and Sleep Quality Insights#

When it comes to physical activities, the comparison between Fitbit Air vs Ultrahuman Air presents two entirely distinct approaches to exercise. While Fitbit Air is equipped with a conventional activity monitor approach, Ultrahuman Air is equipped with an energy management approach.
Daily Activity Tracking and Step Counting #
The Fitbit Air comes equipped with a basic 3-axis accelerometer and gyroscope that helps you record your daily steps accurately with the help of your wrist, but the Ultrahuman Air comes equipped with an extremely sensitive 6-axis IMU sensor which is placed on your finger. While the Fitbit Air comes with good step tracking software that successfully eliminates all false arm movements, the Ultrahuman Air has a small flaw where it tends to mistake the small movements of typing on the laptop keyboard with real walking. Hence, the Fitbit Air is much more accurate for people who are office goers and type all day as compared to the Ultrahuman Air, since it tends to over report your daily step counts if you type heavily throughout your workday.

Therefore, the Fitbit Air is characterized by its more closed software ecosystem, while the Ultrahuman Air features extensive compatibility with other platforms.
Fitbit Air vs Ultrahuman Air Accuracy and Data Insights#
The accuracy of the between Fitbit Air and Ultrahuman Air has a lot to do with how the sensors are placed. This is because the sensors on Fitbit Air include red and infrared sensors, which are placed on the relatively thick skin of the wrist in order to detect SpO2, whereas the Ultrahuman Air includes sensors that are placed on the very thin skin of the finger. The accuracy of the accelerometer data on the Fitbit Air is highly reliable when swinging the arms during runs, while the heart rate data on the Ultrahuman Air is highly accurate due to the closeness of blood vessels under the finger skin.
Also, the Fitbit Air has in-built algorithmic smoothing, which ensures that the data is presented in an elegant manner on the app, but the Ultrahuman Air has raw data points, which provide you with all the minute fluctuations of your body temperature. In terms of accuracy, the Fitbit Air is quite accurate in its readings considering that it is a fitness tracker, but the Ultrahuman Air is highly accurate in providing the research-grade measurements of temperature and HRV.
