Ultrahuman Ring AIR – Smart Ring | Geen maandabonnement | Bepaal eerst de juiste maat met de Sizing Kit | Slaaptracker - Hartslagmeter - Fitnesstracker – Air Gold – Size 5

If you're more interested in keeping a keen eye on your sleep trend and gradual health improvements, you should check out the Ultrahuman Ring Air. Sure, there is an initial cost to buy the ring, but thanks to the lack of subscription fees, you'll be able to access any and all future software upgrades, improved features, and new modes – for free.

Honestly, it is just ok. The color is nice (raw titanium), but it looks massive and awkward on my finger and based on the sizing kit, there was only one finger I could fit it on which isn't ideal (right pointer). The app is ok, almost TMI to really understand it all. The battery doesn't last very long -4 days, and it takes a while to charge so if you're into the data you are losing data. For the price, to me it wasn't worth it. Returning.

Seriously, DO NOT PURCHASE. They have major issues with battery draining in 1-2 days. This is my second ring purchase. The first one purchased in January 2025 with the battery draining to quickly. Exchanged for a second one and within 3 months the ring DOES NOT WORK, won't connect, no bluetooth, can't re-set it because there is no connection. The Ring is DEAD. Returning was difficult because this is my second one. Sounds like they did NOT beta test this device (ring) to ensure all the bugs are out. I would not recommend this product. Ultrahuman has NO human customer service until 45 mins has passed then you get in touch with a human who will take 15 minutes to answer a single question. NOT worth it.

I love it! So much cheaper and just as efficient as the Oura ring, No monthly subscriptions and it's water resistant and I've had mine for a few weeks and I wear it every chance i get. I love how it tracks my sleep so efficiently and tells me how much more sleep I should be getting.

The Ultrahuman Ring Air can track a variety of unique wellness criteria like caffeination and circadian rhythms in addition to core stats like sleep and stress, though it doesn't quite unseat the Oura for best smart ring.
