COROS PACE 4 vs Ultrahuman Ring AIR
Sqwod verdict
Our pick: COROS PACE 4 takes it — 84 vs 82.
Both are strong — the call comes down to what you prioritise:
- COROS PACE 4 — You coach runners or triathletes and want accurate GPS, a readable AMOLED and two-plus weeks of battery at a mid-range price, without Garmin's markup.
- 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 
COROS PACE 4
84Score · Medium
from €267.50
The PACE 3 formula with a bright AMOLED: still ultralight, accurate on GPS and good for up to 19 days, now with a microphone, an action button and, since the September 2026 update, offline maps in beta. It costs about 40 EUR more than the PACE 3 does now, which is the only real catch.
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.
