Higher ratedRanked #2 in Best Smart Rings

Oura Ring Gen 4

4.4

$349

The Oura Ring 4 stands as a top-tier smart ring for holistic health tracking, according to PCMag's Andrew Gebhart and NBC Select's Harry Rabinowitz. It excels in sleep monitoring, heart rate tracking, and body temperature measurement with an 8-day battery life and fully titanium construction. However, the device requires an Oura Membership subscription to unlock full functionality, limiting basic data access. While it's ideal for users seeking comprehensive wellness metrics without a screen, it may not suit those needing detailed workout analytics or built-in GPS. The ring's sleek design and improved sizing options make it a strong contender for health-conscious consumers.

Strengths

— Improved 8-day battery life (up from 7 days)
— Fully titanium build with wider range of sizes (4-15)
— Accurate health tracking including heart rate, sleep stages, and body temperature

Watch-outs

— Requires a subscription for full features; basic data only available without membership
— Not the best for detailed workout data tracking
— No built-in GPS for outdoor activities

Ranked #3 in Best Smart Rings

RingConn Gen 2 Air

4.0

$99

The RingConn Gen 2 Air offers a budget-friendly alternative to premium smart rings, with PCMag's Andrew Gebhart noting its accurate heart rate monitoring and impressive 14-day battery life.

— Affordable price point compared to premium smart rings like the Oura Ring 4
— Accurate heart rate monitoring during workouts and rest
— Waterproof design allows for swimming and showering

Watch-outs

— Limited smart features compared to high-end competitors
— Basic sleep tracking without detailed insights or coaching

How they stack up

Oura Ring Gen 4

The Oura Ring Gen 4 offers the most comprehensive health tracking and longest battery life of the group, but it requires a subscription unlike the RingConn Gen 2 Air, which provides basic tracking without one. While it's more accurate than the Samsung Galaxy Ring in health metrics, it lacks the lightweight comfort of the Ultrahuman Ring Air and GPS capabilities.

RingConn Gen 2 Air

The RingConn Gen 2 Air offers the most affordable option among the smart rings, but it lacks the advanced features and accuracy of the Oura Ring Gen 4 and Samsung Galaxy Ring. While it matches the Oura Ring 4 in battery life, it falls short in sleep tracking insights and health monitoring precision, making it a basic alternative for budget-conscious buyers.
