I found a subscription-free smart ring that rivals Oura - and it's discounted at Walmart
Briefly

The Ultrahuman Ring Air, recently discounted at Walmart, is a competitive smart ring designed for fitness enthusiasts and casual exercisers alike. Unlike the Oura Ring, which relies on a monthly subscription, the Ultrahuman Ring is subscription-free and provides comprehensive health tracking features. After testing both rings concurrently, the Ultrahuman stood out for its durability and discreet design. Its notifications help users optimize their energy and body clock, making it a compelling choice in the expanding smart ring market.
Unlike the Oura Ring, which requires a $6 monthly subscription, the Ultrahuman Ring Air is subscription-free.
Suffice it to say, the Ultrahuman ring will excite people dialed into their health and fitness.
The Ultrahuman comes in matte gray, matte black, silver, and gold. Out of all the smart rings I have tested, it is by far the thinnest, most discreet, and unassuming.
Ultrahuman is sending you notifications on how to make the most of your available energy and body clock.
