The Circular Ring 2 is poised to redefine wearable health technology, offering groundbreaking features that could surpass even the best Android smartwatches. After a highly successful Kickstarter campaign, which raised over $1 million, Circular has announced two major health-tracking upgrades that will roll out in the coming years.
Blood Pressure Monitoring Like Never Before
One of the most significant updates for the Circular Ring 2 will be spot blood pressure measurements, set to launch by the end of 2025. Unlike traditional wearables, this smart ring will use a combination of ECG and PPG technology to estimate blood pressure with greater accuracy.
The technology behind this involves measuring Pulse Transit Time (PTT)—the time it takes for blood to move through your arteries. This non-invasive method could revolutionize how users track their cardiovascular health, all from a compact, lightweight ring.
Blood Glucose Trend Tracking in 2026
Looking even further ahead, Circular plans to introduce blood glucose trend tracking to the Ring 2 by late 2026. This feature will utilize PPG sensors and AI-driven machine learning to analyze how light interacts with blood, giving users insight into glucose level fluctuations.
However, Circular clarifies that this will not replace traditional glucose monitors or CGMs. Instead, it will help users understand how their activity levels impact blood sugar trends, enabling better lifestyle choices.
What Sets Circular Ring 2 Apart?
With these upcoming updates, the Circular Ring 2 stands out in the wearable market by offering features that even top Android smartwatches lack. While other smart rings focus primarily on sleep and fitness tracking, Circular is pushing the boundaries with blood pressure and glucose trend monitoring.
Launch Timeline & Availability
Currently available via Kickstarter, the Circular Ring 2 is slated for mass production in April 2025, with shipments expected between June and July. However, users eager to try its most advanced health features will have to wait until late 2025 and 2026 for the software updates to roll out.
While the Ring 2’s accuracy is yet to be proven, its ambitious feature set makes it one of the most exciting wearable releases to watch in the coming years.
