A French company, Circular, is set to launch the Circular Ring 2, touted as the world’s most advanced health tracking ring. It will feature innovative blood pressure and blood glucose monitoring capabilities, integrating photoplethysmography with electrocardiography and machine learning. Pre-orders are available through a Kickstarter campaign, with prices starting at $239. The ring is expected to be delivered in mid-2025, and significant advancements could position it ahead of competitors like Apple and Samsung.
Revolutionary Health Tracking with Circular Ring 2
Often overlooked, a French company specializing in connected rings is set to introduce two groundbreaking health features that have never been seen in such accessories. The launch of Samsung’s Galaxy Ring has sparked interest in smart rings, bringing brands like Oura and Ultrahuman into the limelight. Even tech giant Apple is preparing to release its own version. While many smart rings share a similar aesthetic, some brands are striving to differentiate themselves by offering unique functionalities.
Innovative Features of the Circular Ring 2
Circular, the French innovator, has unveiled its Circular Ring 2, claiming it to be “the most advanced health tracking ring in the world.” This bold assertion is backed by the ring’s ability to measure blood pressure and blood glucose levels, which no other competitor in the market has accomplished with precision.
The Circular Ring 2’s blood pressure measurement leverages a novel approach. While many connected devices utilize photoplethysmography (PPG) for this purpose, the results are often rough estimates. Circular plans to enhance accuracy by combining PPG with electrocardiography, utilizing Pulse Transit Time (PTT) — the duration it takes for blood to flow through arteries. Users will have the ability to capture measurements in just 30 seconds to 2 minutes throughout the day, allowing them to see how their blood pressure fluctuates during various activities such as meals or exercise. This feature is expected to be activated via a software update by late 2025.
Regarding blood glucose monitoring, this feature will also be rolled out through a software update, anticipated by the end of 2026. This non-invasive method will analyze how light interacts with blood, merging PPG technology with advanced machine learning algorithms. While Circular acknowledges this method is not a substitute for traditional medical tests, it offers a promising way to monitor blood sugar fluctuations.
The Circular Ring 2 is projected to launch in the summer of 2025. If Circular follows through on its commitments, it will provide functionalities that are currently unmatched by Apple, Google, or Samsung in their smart accessories. As always, real-world testing will be necessary to confirm these capabilities, but the potential of a ring with such advanced features is certainly exciting, and we remain hopeful for favorable outcomes.
For those interested in pre-ordering the Circular Ring 2, the device is available through its Kickstarter campaign. The initial funding goal has been surpassed, ensuring the product will be realized. Early buyers can secure the ring starting at $239 (approximately €220), with no subscription fees required for accessing its features.
Keep in mind, this is the introductory price for early supporters, and it may increase as the campaign progresses. The crowdfunding initiative concludes on April 14, 2025, with delivery expected between June and July of the same year.
