French startup Circular unveils promising Oura fitness-tracking competitor

Add as a preferred source on Google

Several smartwear products took the center stage at CES 2022. Apart from the heavy hitters such as Garmin and Skagen, a Movano ring was also unveiled, with a design that specifically has female users in mind. Finally, a French company called Circular also unveiled its first product, simply called the Circular Ring. 

The Circular Ring has changeable outer shells for user customization. The ring is extremely lightweight at only 4 grams. It is also water-resistant up to 5 meters. It also offers up to 22 days of built-in data storage without a Bluetooth connection. The biocompatible resin-based product will be available in different sizes.

Tracking and features

A 14-day calibration period begins as soon as the user wears the ring for the first time. During this period, the ring establishes the user’s baseline health parameters, which helps it to give them personalized and actionable recommendations to make healthy changes in their lives. Circular tracks multiple health metrics, including temperature, heart rate variability, energy levels, and VO2 Max.

Circular has a dual PPG sensor in its ring combined with the Circular app that allows it to read heart signals and blood oxygen. It detects if the heart rate shows any signs of cardiac arrhythmia, and if the heart rhythm is steady. The data tracked is purported to be clinically accurate and can be shared with a professional for further advice. Wearing it both during the day and the night can help Circular to correlate the data using machine learning.

Circular also seems to be extremely efficient while tracking sleep. It can tell a user how much time they spend in each sleep stage — light sleep, deep sleep, REM sleep, and when they are lying awake. More importantly, it also calculates how efficiently a user has slept. The app shares data on a number of important criteria to examine sleep quality, including time taken to fall asleep, sleep debt, real sleep time, disturbances while sleeping, etc. It also provides silent vibrations to users in their light sleep stage if they wish to be awakened, without disturbing their surroundings.

Price and availability 

A single charge of the ring gives it four days of battery life. A single charge from 0% to 100% can be completed in one hour. Pre-orders, which will begin soon, will run until February 27, 202. The device will have a cost of 259 euros ($293) during that time. Starting February 28, the price will jump to 289 euros ($327). Shipping and other details are expected to be announced soon by the company.

Shared Albums in iOS 27 feels like a private social media universe of its own, and I love it
No algorithm. No strangers. No follower count. Just the people you actually want to share things with.
Electronics, Phone, Mobile Phone

It has been a year since I uninstalled Instagram from my phone and reclaimed about two hours of my time every day. I was tired of seeing what random people were up to on the weekend, how I was still filing articles on a Sunday, and quietly getting jealous of people I don’t even know.

What I’d rather have any day is a place to share and relive moments with people I genuinely care about, without an algorithm, strangers, or the dopamine trap. Oddly enough, iOS 27’s Photos App comes with an overhauled Shared Albums that is exactly that. Ever since I started using it, I haven’t looked back.

Ahead of Apple, Caviar is showing off the foldable iPhone Ultra with a tinge of luxury
The yet to launch iPhone Ultra is already getting a 19-unit luxury run from Caviar
Apple iPhone Ultra Custom Caviar models

Apple has not announced its first foldable iPhone yet, but Caviar is already trying to sell a luxury version of it. The custom phone brand has revealed its “Flagship” collection for the rumored iPhone Ultra, giving Apple’s expected foldable a gold, silver, leather, and carbon fiber makeover months before the real device is likely to appear.

Caviar has made plenty of wildly expensive Apple accessories and custom phones before. We recently saw the company put a Tyrannosaurus fossil fragment into a $4,490 magnetic case for the iPhone 17 Pro Max. Its foldable iPhone Ultra collection is playing in the same absurdly expensive territory, only this time the luxury treatment is arriving before Apple’s own version.
