According to the PCMag review, the Circular Ring 2 introduces next-generation health tracking features such as FDA-approved electrocardiograms (ECG) and atrial fibrillation (AFib) detection in a lightweight titanium band. Despite its ambitious functionality, the device's inconsistent accuracy and frequent app instability limit its current usefulness compared to established competitors in the smart ring market.
- Advanced ECG and AFib monitoring integrated into a smart ring
- App instability and inaccurate tracking metrics reported
- No subscription currently, premium features planned
Product angle
The PCMag review outlines that Circular Ring 2 aims to stand out in the wearable market by offering advanced health sensors including FDA-cleared ECG and atrial fibrillation detection directly from the finger, a rare feature in wrist-worn devices. Although this reflects an ambitious approach to smart ring capabilities, the review points out that critical fundamentals such as app stability and syncing speed have not been fully realized. These issues introduce user frustrations and diminish trust in the data accuracy.
The device is made from titanium and comes in multiple stylish finishes, displaying a design-led ethos. However, several exercise and sleep metrics were either missing or unreliable during testing, which is a significant drawback for users relying on consistent fitness data. The app also crashed multiple times, indicating software maturity concerns. Overall, the Circular Ring 2 appears to be a promising but undercooked health device in its current form.
Best for / avoid if
This product may appeal to early adopters and health tech enthusiasts interested in pioneering smart ring technology with high-tech heart monitoring features delivered in an elegant form factor. Users looking to track ECG and chronic atrial fibrillation non-invasively might find it a unique option not broadly available on competing wearables. Its current no-subscription model also attracts users wary of ongoing fees.
Potential buyers should avoid the Circular Ring 2 if they require consistently accurate fitness and sleep tracking or demand a stable and user-friendly app experience. Those who prioritize reliable data for fitness regimes or who dislike troubleshooting buggy software will likely be frustrated. Additionally, users needing blood pressure or glucose measurements will have to wait for future software updates that enable these functions.
Pricing and alternatives to check
The Circular Ring 2 starts at $349 for the black titanium finish with higher tier colors priced at $449 to $549. Unlike some competitors, it currently carries no subscription fees, though Circular plans to introduce a premium tier subscription to unlock advanced features such as detailed blood pressure and glucose monitoring in the future. The company has not disclosed pricing for this service, proposing a unique freemium model with potentially earned credits to pay fees.
Key alternatives include the Oura Ring 4, noted by PCMag as a superior option in accuracy and overall value at the same $349 price, though it requires a subscription for full data access. Samsung Galaxy Ring offers a comparable ring priced around $399.99 with free sizing kits and no subscription fees. Buyers should compare these products based on stability, feature completeness, and long-term cost implications before deciding.
