It connects via Bluetooth v5.0 and lasts 4 to 6 days on a full charge. Water resistance up to 100 meters for 12 hours allows for use during swimming or showering, and advanced sensors enable features like circadian rhythm tracking, temperature-based ovulation prediction, and AFib detection.

At a glance

The Ultrahuman Ring Air is a lightweight smart ring that tracks sleep, heart rate, steps and skin temperature in a discreet form factor. It suits people who want health insights without wearing a smartwatch, especially for all-day and overnight use. Key strengths include comfort, durable titanium construction and up to 4 to 6 days of battery life. The main limitation is its smaller ring-style format offers less on-device interaction than watch-based trackers.

Who it’s for

Things to consider

Compared with smartwatch-style fitness trackers, the ring format provides less screen-based feedback and fewer on-device controls, so most insights are accessed through the companion app.

Beginner vs athlete fit

Best for beginners to intermediate fitness users and wellness-focused wearers, though athletes can still use it for recovery and sleep tracking.

Health monitoring depth

8.5/10 - Tracks heart rate, sleep, steps, skin temperature, circadian rhythm, ovulation-related temperature changes and AFib detection.

Smartphone compatibility

iOS and Android

Battery endurance rating

8/10 - Lasts 4 to 6 days on a full charge, which is strong for a compact ring-style tracker.

Water resistance score

9/10 - Water resistant up to 100 meters for 12 hours, making it suitable for swimming and showering.

Q: Is Ultrahuman Ring Air size 05 the same as a standard jewellery ring size?

A: No. Smart ring sizing can differ from standard jewellery sizes, so size 05 should be matched using the Ultrahuman sizing method before purchase. It is best to size the finger you will actually wear it on, as finger width can vary across hands.

Q: Does the Ultrahuman Ring Air work with both iPhone and Android phones?

A: Yes. Ultrahuman Ring Air pairs with the Ultrahuman app on compatible iPhone and Android phones and syncs over Bluetooth. It is designed for regular app use, so setup, insights and firmware updates depend on having a supported mobile operating system.

Q: Does the Ultrahuman Ring Air require a paid subscription to use its tracking features?

A: No. Ultrahuman Ring Air is generally sold without a mandatory ongoing subscription for core tracking and app access. You still need the companion app and an account for setup and syncing, so it is not intended as a standalone ring without a phone.

Q: Can the Ultrahuman Ring Air be worn during gym sessions or weight training?

A: Yes, but heavy gripping exercises can make any smart ring less comfortable and may mark the finish over time. For weights, kettlebells or pull-ups, many users remove the ring to avoid pressure on the finger and reduce cosmetic wear.

Q: Is the brushed rose gold version different in features from other Ultrahuman Ring Air finishes?

A: No. The brushed rose gold version changes the look of the ring, not the core tracking purpose of the Ring Air range. The main buying decision is fit and finish preference, because comfort and sizing matter more day to day than the colour.
