Our verdict
For most buyers, the Pebble Index O1 delivers better value at $249 with its innovative AI features and gesture controls, earning a strong 91 DriftScore. However, if comprehensive health tracking is your priority, the Oura Ring 4's superior sleep analysis and blood oxygen monitoring justify its $299 price tag and slightly higher 92 DriftScore.

Frequently asked questions
Which smart ring has better battery life?
Both rings typically last 5-7 days on a single charge, but the Pebble Index O1's on-device AI processing may drain battery faster during heavy voice note usage. The Oura Ring 4 offers more consistent battery performance for continuous health tracking.
Can I use either ring without a subscription?
The Pebble Index O1 works fully without ongoing fees, while the Oura Ring 4 requires a $5.99/month subscription after the first month for advanced features. This adds $72 annually to the Oura's total cost of ownership.
Which ring is more accurate for fitness tracking?
The Oura Ring 4 has more proven accuracy for heart rate, sleep stages, and blood oxygen monitoring with years of algorithm refinement. The Pebble Index O1 focuses more on AI interactions and gesture controls rather than comprehensive fitness metrics.
