Circular™ Smart Ring | Sleep, Energy, Performance. Evolved. | Technology 2020

24/7 activity, sleep, and wellness monitoring with personalized recommendations, smart & silent alarm clock alerts with style.


Circular is the smart ring that combines style with cutting edge technology to empower you to be more energetic and productive.

On the outside, Circular is sleek, seamless, and discreet. On the inside, it’s powered by advanced mechanical customization and intuitive AI.

When it comes to user experience, we’ve made no compromises. The result? A seamless experience that works for you day & night.

Can we introduce you to someone very special? Meet Kira. She’s an integral part of the Circular experience, and her whole goal is to make your life easier—from helping you make improvements to letting you know when it’s time to step it up.

Circular never sleeps, but you’ll sleep better.

That’s because what Circular does best is synthesize and analyze your body signals (night and day!) for unique recommendations and advanced wellness correlations to improve your well-being.

Circular Tracks:

While designing Circular, our wish was to create a device that would assist us in responding to our body signals in a healthier way—helping us make optimal daily activity choices instead of just measuring the metrics. With Circular, you can learn about the effect of your sleep on your daily performance and the effect of your activities on the quality of your sleep and your future wellness.

Everyone is unique, whether it is in terms of lifestyle, fitness, thoughts, choices, recovery, health, or sleep patterns. Circular’s tracking features hold their true benefits in our cross-analysis. Day & Night tracking combined enables us to deeply understand how the body reacts to events and what it needs.

We’ve spent a whole year working with sleep and activity specialists, doctors, and PhD. students to develop algorithms that effectively analyze your body signals in line with laboratory equipment.

The precision can only get better with time, making Circular one of the most accurate and noninvasive tracking devices on the market.

Get real-time, personalized recommendations. Control your ring, visualize your progress, meet (and compete with!) your wellness community, and get impactful recommendations through the Circular app.

We’re taking wearable tech to the next level by establishing baselines for users instead of just measuring metrics and spitting out raw data. Through the Circular app, you’ll be able to:

Control your ring.
Measure and visualize your progress through our sleep and activity scoring system.
Meet (and compete with!) your fitness community.

When working out, we don’t want to wear a device made of precious gems; neither do we want to wear a plastic-looking device to an elegant event.

We believe that wearables should seamlessly blend into our everyday lives, and that’s exactly what Circular does.

It’s scratch-resistant, water-resistant, and you can switch up your style to fit the occasion with interchangeable outer shells.

Need a charge? Connect on-the-go with our mobile charging solution.

The Circular ring connects via Bluetooth to your iPhone or Android device. Setting up the ring is as easy as downloading the app onto your phone, and all software updates are wirelessly transmitted to your Circular ring.

Built-in intelligence
We designed Circular to be an effortless, autonomous part of your daily life. There’s no on/off button on the ring; it knows whether you are wearing it or not. Similarly, there’s no need to notify the app nor the ring about what you are going to do. Circular knows when you go to sleep and when you do activities, and it uploads the subsequent data to your phone automatically. If your phone is not available, it can collect and store detailed data for up to 7 days.

Body Signal processing
The ring collects the body signals it needs using its dual sensors (Heart Rate Sensor and Accelerometer). Circular contains a built-in processor that will process the data and send it by Bluetooth to the Circular mobile app for analysis. The Circular app uses machine learning to better understand your habits and offer a personalized experience.

Wave free during your sleep
Although the 2400 MHz to 2485 MHz radiation output of a Bluetooth device is negligible to your health, the Circular ring automatically goes into “sleep mode” when it detects a sleeping state⁠—meaning that it is functioning without Bluetooth during your sleep while still capturing your body signals. It will synchronize with the app when you get up.
