Apple Watch Series 12 vs Ultrahuman Ring AIR
Sqwod verdict
Our pick: Apple Watch Series 12 takes it: 84 vs 82.
Both are strong: the call comes down to what you prioritise:
- Apple Watch Series 12: You're on a Series 9 or older and want the most accurate wrist heart rate Apple has made, plus a readiness score you can use to steer clients' training, with no subscription.
- Ultrahuman Ring AIR: You want continuous sleep, recovery and HRV data (with an optional metabolic angle) without locking clients into a monthly subscription.
Our pick 
Apple Watch Series 12
84Score · Medium
from €434
The new Health Sensing System is the real upgrade: heart rate every five seconds, far more frequent HRV and a daily Readiness score, with testers finding it close to a chest strap. Battery is still rated at 24 hours and the design is unchanged, so Series 11 owners can skip it.
Ultrahuman Ring AIR
82Score · Medium
from €234.53
An accurate, feather-light recovery ring with a standout metabolic-health angle, and, unlike Oura, no subscription. Softer workout tracking is the trade.
