Smart rings are the new smartphones. Well, almost. While smartwatches are still stuck in the “daily charging + endless notifications” phase, health technology is slowly but elegantly moving to your fingers – literally. The Circular Ring 2 is the latest player on the scene, not only measuring your vital signs with near-medical precision, but also interpreting them meaningfully with the help of its own free (!) AI trainer. No graphs that look like they came from a NASA control room. No subscriptions that bite a big chunk out of your wallet every month. Just pure data – and most importantly, what that data means to you.
The doctor doesn't just hand you a sheet with your blood pressure and say, "Well, now figure it out for yourself." No, the doctor gives a diagnosis. Then a prescription. Circular Ring 2 works the same way: data → analysis → concrete suggestions for improvement. At the heart of this story is Kira - your personal, hyperintelligent AI trainer, who won't force you to take 10,000 steps a day if you can barely find time for your morning coffee. He'll suggest a short meditation if he senses you're about to have a nervous breakdown.
What does this little titanium miracle know?
Unlike watches that measure data from the wrist (where signals are weaker and more distorted), Circular Ring 2 picks up signals from the finger - where blood flow is stronger and the data is more reliable. And because in this world, things count everything little things, the ring will monitor you with 140+ biometric measurements. Among them: heart rate, heart rate variability (HRV), sleep quality, SpO₂, body temperature, stress level, breathing and more.
Good sleep? Check. Stress reduction? Sure. Optimizing post-workout recovery? Of course. And if you're worried, how often does it measure? Every 2 minutes, which is about 5 times more than classic fitness trackers. Practically a little digital doctor who doesn't sleep (even if you finally start).
AI without “subscription trauma”
In a world where every useful piece of information is hidden behind a paywall (hello, Google Fitbit and Oura), the Circular Ring 2 offers a liberating alternative: no monthly subscriptions, no hidden costs. One payment = all features, forever. Everything included: stress analysis, personalized guidance, integration with Apple HealthKit and Google Health Connect – and your data stays yoursNo questionable sharing with third parties – GDPR is the law, literally.
Charging? Maybe once a week. Maybe.
While smartwatch owners religiously plug their devices into their chargers every night, the Circular Ring 2 takes a more Zen approach. A week of battery life without a hitch. And if you have their sleek charging case, you can forget about the outlet for almost a month. So, yeah – for once, a device that’s more “smart” than “always on a cable.”
A design you wouldn't be ashamed of even on the red carpet
Circular Ring 2 is made of lightweight titanium and comes in four colors: Obsidian Black, Gold, Silver, and Rose Gold. It’s completely waterproof, so don’t worry about swimming, running, or just sweating it out in a meeting—the ring will survive. Sizes 5 to 13? Sure. And instead of sending plastic measuring kits through the mail (another package, another waste), measure your ring right on your phone—in seconds.
Why now? Why this one?
The Circular Ring 2 is currently available on Kickstarter for a ridiculously low $$239 (down from a regular price of $$550). Compared to the Oura Gen 3, which has a higher starting price and a monthly fee, this is almost a no-brainer. With over $1.2 million in funding raised and the growing popularity of smart rings, it's clear: this is the future. And Circular Ring 2 shows how good that future can be – small, elegant, smart and finally without ongoing costs.
Summary for the impatient:
- The first smart ring with ECG
- No subscriptions, everything included
- AI trainer Kira = your new wellness guru
- 140+ biometrics measured every 2 minutes
- 1 week of battery, 0 notifications, 100 % peace of mind
- Early bird price: $239 (instead of $550) on Kickstarter
If smart rings are the next generation of wearable technology, then the Circular Ring 2 isn't just following the trend, it's leading it. And for once, it doesn't look like it's stopping.
