Circular’s upcoming smart ring, the Circular Ring 2, will get blood pressure tracking via an OTA update in late 2025.
The ring is also expected to introduce non-invasive blood glucose trend tracking in late 2026.
The Circular Ring 2 is available for pre-order on Kickstarter for $239, with no additional subscription fees.

The smart ring market is rapidly evolving, with players like Oura setting the standard and tech giants like Samsung entering the fray with the Galaxy Ring. Now, Circular is pushing the category forward with bold new claims for its latest wearable, the Circular Ring 2, which is set to launch later this year.

The company recently opened pre-orders for the Circular Ring 2 on Kickstarter, surpassing the $1 million mark in pledges. Alongside this milestone, Circular has announced two major health-tracking features coming to the device post-launch: blood pressure (BP) and blood glucose (BG) trend tracking. These additions, arriving via over-the-air (OTA) updates in late 2025 and 2026, respectively, could significantly expand what smart rings are capable of.
