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. Tom's Guide praised it for beating the Oura Ring 4 in three key areas, particularly its affordability and basic functionality.

This ring is best suited for users seeking basic health tracking without the premium price tag, but those wanting comprehensive sleep coaching or GPS should look elsewhere.

— Accurate heart rate monitoring during workouts and rest

How they stack up

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.

Ultrahuman Ring Air

The Ultrahuman Ring Air provides the most accurate heart rate monitoring and longest battery life, but it's more expensive than the RingConn Gen 2 Air and lacks third-party app support compared to the Oura Ring Gen 4. While it's lighter than the Oura Ring 4, it doesn't offer the same level of sleep insights or ecosystem integration as the Samsung Galaxy Ring.
