What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Oura Ring 4
Four testers (Tom's Guide, TechRadar, Engadget, Digital Trends) all hands-on-tested the Oura Ring 4 and call it the best smart ring you can buy, praising the all-titanium comfort and companion app. Every source flags the mandatory ~$5.99/month subscription; easy scratching and step/calorie/activity-detection accuracy are the recurring doubts across reviews. (4 sourced reviews, 4 lab-tested.)
Praised: Comfortable all-titanium design with flush, recessed sensors; Excellent companion app with clear data presentation; Long real-world battery life (roughly 5.5-7 days per charge).
Flagged: Mandatory ~$5.99/month subscription to unlock most features; Step / calorie / activity-detection accuracy lags a smartwatch; Titanium surface scratches easily within weeks.
