Long-Term Review: Is the Oura Ring 4 Worth the Upgrade?

After nearly four years of consistent use, including a full pregnancy and postpartum recovery, the Oura Ring 4 has proven to be a significant evolution over its predecessor. While the initial transition from the third generation raised questions about whether the $100 price increase was justified, long-term testing reveals that the hardware improvements—specifically the enhanced sensor array and the all-titanium build—offer tangible benefits. The most notable upgrade is the battery life, which now requires charging only once per week, effectively eliminating the data gaps that plagued earlier models.

Beyond the hardware, the Oura ecosystem has matured, with the company focusing on software updates that improve data accuracy. The refined sensor array has successfully addressed common issues, such as misidentifying daily tasks like washing hair as high-intensity workouts. This level of precision is critical for users who rely on the ring for health tracking, particularly during major life transitions where baseline biometrics fluctuate significantly. The device remains a top choice for those who prefer a discreet, non-wrist-based wearable, especially as the smart-ring market continues to expand with increased competition.

For prospective buyers, the sizing process remains a crucial step, as Oura 4 sizing differs from previous generations. While the lack of half-sizes remains a minor drawback, the flexibility to wear the ring on different fingers without sacrificing significant accuracy provides a more comfortable user experience. Ultimately, the Oura 4 represents a shift toward more reliable, long-term health monitoring, proving that the value of the device lies as much in its consistent data collection as it does in its sleek, durable design.
