How alternatives compare to Oura Ring 4
RingConn Gen 2 Smart Ring Size 10
The RingConn Gen 2 Size 10 offers detailed sleep apnea tracking, a feature not highlighted for the Oura Ring 4. It operates on a subscription-free model, which contrasts with the Oura Ring 4’s required monthly membership. Both rings target women and support Android and iOS. However, the RingConn Gen 2 is significantly heavier at 13.4 ounces compared to the Oura Ring 4’s 6.35 ounces. You should choose the RingConn Gen 2 if you prioritize deep sleep apnea analysis and want to avoid recurring fees. The Oura Ring 4 remains the better option if you prefer a lighter device and value the established Smart Sensing ecosystem.
QALO SR-1 Titanium Smart Ring Size 7
The QALO SR-1 Titanium Smart Ring Size 7 is built from titanium, offering durability that the Oura Ring 4 may not match. Like the Oura Ring 4, it includes women’s health tracking and works with both Android and iOS. Crucially, it requires no subscription, unlike the Oura Ring 4 which charges a monthly fee after the first month. The QALO SR-1 is available in size 7, whereas the reference Oura Ring 4 is size 10. If you want a rugged build and dislike subscription models, the QALO SR-1 is a strong alternative. The Oura Ring 4 is better if you need a larger size and the specific Smart Sensing features.

The Oura Ring 4 Size 4 is designed for users needing a smaller fit, with a width of 0.87 inches compared to the 1.06 inches of the Size 10. It shares the same 0.28-inch height and Silver color. This model also provides up to 8 days of battery life and tracks sleep, activity, stress, and heart health. It requires the same monthly subscription as the larger Size 10. You should pick the Size 4 if your finger size is smaller. The Size 10 is better for larger fingers. Both offer identical tracking capabilities and battery performance, differing only in physical dimensions to ensure a proper fit.
