This Oura Ring rival is $55 off during Prime Day -- no subscription necessary
The Ultrahuman Ring Air is a subscription-free smart ring that rivals the Oura Ring, and it's less than $300 on the second day of Prime Day.
I tested one alongside the Oura Horizon ring this past month, wearing both around the clock, and logging everything from my morning coffee to my late-night cocktails. The last feature that makes this ring ideal for exercise junkies is the Discover tab, which offers video classes for everything from Pilates and weight training to HIIT and yoga. It could take some notes from Oura's app, which offers sleep, readiness, resilience, and activity on top of a home tab that aggregates this data on the bottom.
