Circular Ring 2: Extra Costs for Blood Pressure and Sugar Analysis
Key Takeaways
1. Circular Ring 2 launched on Kickstarter, with the first 1,000 units shipped after a successful campaign.
2. The ring is priced at $249, making it more affordable than the Oura Gen 4, which costs $349.
3. It offers advanced features like ECG, blood pressure, and estimated blood sugar level measurements.
4. Blood pressure and blood sugar features now require payment through microtransactions or “Circular Coins.”
5. Circular Ring 2’s core features remain free, and users can earn Circular Coins through regular use of the ring.
Circular Ring 2 was funded through Kickstarter in the spring, and last week, the first 1,000 units were shipped to supporters. The ring was priced starting at $249 during the campaign, making it much more affordable compared to the Oura Gen 4, which retails for $349 on Amazon.
Advanced Features
The main aim was to surpass rival products by offering more analytics: the ring claims to perform electrocardiograms (ECG) and assess blood pressure and blood sugar levels. Blood pressure is measured using a heart rate sensor and ECG, much like the Samsung Galaxy Watch8, which likely means it will need calibration with a standard measuring device. The blood sugar level is merely “estimated,” so the information it gathers can only serve as a rough guideline.
Subscription Concerns
Although Circular Ring 2 was marketed during the Kickstarter campaign as not needing a subscription, the two standout features—blood pressure and blood sugar measurements—are now behind a paywall. To access these features, users must engage in microtransactions or spend “Circular Coins.”
As these features are set to be available only after an update anticipated at the end of the year, it’s still uncertain how much they will cost. Backers expressed their frustrations in the Kickstarter comments, noting that Circular Ring 2 was originally promoted without any ongoing fees. In response, Circular emphasized in a statement that the 13 “core features” of the ring remain free, and users can also “earn” Circular Coins by using the ring without any additional spending.

Circular Ring 2: Smart Ring with ECG, Skin Temp Sensor, No Fees
Key Takeaways
1. The Circular Ring 2 is available for pre-order on Kickstarter, with a “Super Early Bird” price of $239 and deliveries starting in June 2025.
2. The ring comes in US sizes 6 to 13 and offers color options including silver, black, gold, and rose gold, with a battery life of up to seven days.
3. It features an FDA-approved ECG for heart rhythm monitoring and tracks heart rate, skin temperature, SpO2 levels, and more.
4. All features can be used without subscription fees, unlike some competitors, and it includes a smartphone app with an AI assistant named Kira.
5. The ring is made from titanium, is waterproof up to IP68 standards, and weighs approximately 0.14 ounces.
The Circular Ring 2 was first announced last November, and now, it’s ready for pre-order on Kickstarter. Customers can expect deliveries to start in June 2025. The “Super Early Bird” price is set at $239, while the retail price is anticipated to increase to $550, not including shipping or any international import fees.
Availability and Features
This smart ring comes in US sizes ranging from 6 to 13 and is available in silver, black, gold, and rose gold. A charging case and a cable will be included with each order. The ring reportedly has a battery life of up to seven days, but when using the charging case, this can extend to a full month before needing to recharge.
Health Tracking Capabilities
One of the major highlights of the Circular Ring 2 is its built-in electrocardiogram (ECG), which has FDA approval and can identify specific heart rhythm irregularities. Additionally, the ring automatically tracks heart rate, skin temperature, and SpO2 levels every two minutes to keep a close eye on these metrics throughout the day. It is also capable of measuring heart rate variability, stress levels, menstrual cycles, sleep quality, and workouts.
Subscription-Free Usage
The maker of the Circular Ring 2 points out that all features can be accessed without any subscription fees, which seems to be a dig at the Oura Ring 4 (priced from $347 on Amazon). The ring works alongside a smartphone app that includes an AI assistant named Kira, providing health advice based on the data collected. Constructed from titanium, the ring is also waterproof up to IP68 standards and weighs about 0.14 ounces.

Smart Titanium Ring with ECG: Circular Ring 2 vs Oura & Galaxy Ring
The Circular Ring 2 features a completely revamped design where the sensors and battery are now smoothly incorporated into the round casing, moving away from the flat edge seen in the earlier model. This change aims to enhance comfort while wearing it, although the new version lacks a vibration motor for haptic alerts, likely due to space constraints.
Color Options and Build Quality
You can choose the ring in four stylish colors: gold, rose gold, black, and silver. The titanium version now boasts a sleek high-gloss appearance. The sturdier housing and a fully redesigned app are anticipated to address some of the main complaints associated with earlier models. The battery life remains at an impressive eight days, matching that of the Circular Pro and significantly outlasting the Circular Slim.
Technical Specifications and Features
Although the full technical specifications have not been disclosed yet, the company hints at enhanced sensors and an integrated electrocardiogram feature, which aims to identify atrial fibrillation. Like many “smart” devices emerging in 2025, Circular is promoting a variety of AI functionalities, with the standout being the upgraded Kira+ AI assistant designed to assist users in reaching their personal objectives.upgraded Kira+ AI assistant designed
Pricing and Launch Information
The Circular Ring 2 is set to be funded through a crowdfunding campaign starting in February or March, with a price of $380. This places the Circular Ring 2 at a slightly lower price point compared to the Oura Gen 3 and Oura Gen 4.
