Ultrahuman Ring AIR vs Whoop 4.0
Sqwod verdict
Our pick: Whoop 4.0 takes it — 85 vs 81.
Both are strong — the call comes down to what you prioritise:
- Ultrahuman Ring AIR — You want continuous sleep, recovery and HRV data — with an optional metabolic angle — without locking clients into a monthly subscription.
- Whoop 4.0 — You coach performance and program by daily readiness and strain.
Ultrahuman Ring AIR
81Score · Medium
from €289
An accurate, feather-light recovery ring with a standout metabolic-health angle — and, unlike Oura, no subscription. Softer workout tracking is the trade.
Our pick
Whoop 4.0
85Score · High
from €30
The coach's strain-and-recovery band — screenless, always-on, built for athletes who train by readiness. The subscription model is the commitment.
