## What reviewers say

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. (Based on 4 reviews, 4 lab-tested, 2024-10-17–2025-11-03.)

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); Class-leading, highly accurate sleep tracking.
Flagged: Mandatory ~$5.99/month subscription to unlock most features; Step / calorie / activity-detection accuracy lags a smartwatch; Titanium surface scratches easily within weeks; Finicky sizing — size can feel loose despite the sizing kit.
Disagreement: Measured battery life varied by reviewer and ring size — Engadget wrung ~7 days from a size 10, TechRadar only 5.5 days from the same size, with Tom's Guide and Digital Trends landing at 6; none consistently hit Oura's advertised 8 days. Enthusiasm also split: Tom's Guide ('gold standard') and TechRadar ('nearly perfect') were effusive, while Digital Trends called the hardware 'treading water,' leading rivals 'only by a thin margin.'
