Pretty much what we’re all after.

But does it deliver as promised?

In this Circular Ring review, we will take a deep dive into the features and benefits, as well as the shortcomings, to help you decide if this ring is a good fit for you. Pun intended.

What Is The Circular Ring?

In a nutshell, the Circular Ring is a smart ring that continuously monitors your bio-signals and alerts you if anything going on internally with you is unusual.

Like many cool wearable tech gadgets, Circular was placed on Kickstarter, where it raised over €300,000 from over 1,500 backers.

If you order today, the anticipated delivery target is May 2023. 

Below, we’ll go into specifics on areas of your health that the ring monitors.

What Does The Circular Ring Do?

The Circular Smart Ring focuses on three main areas:

  • Sleep
  • Activity
  • Health

The device tracks your precise heart rate, breathing rate, blood oxygen levels, temperature, and motion during sleep with a focus on quality, duration, and circadian rhythm.

It will even notify you if you have an irregular heart rate and unusual blood oxygen levels.

Here is a breakdown of the three primary functions:

1. Sleep Function

Circular analyzes your bio-signals during sleep to help you keep track of your sleep efficiency.

You can track and learn what parameters impact your sleep and how it correlates with your daily routine.

Using this data as feedback will allow you to improve the quality of your sleep.

There is also a smart alarm that allows you to wake up silently to vibrations. Pretty cool.

Sleep Analytics

Sleep quality score: This score reflects how well you slept based on valuable metrics calculated during your sleep.

Sleep overview: The overview shows you the times you slept, and tracks it in your sleep logs.

Sleep metrics: See the result of each sleep component so that you can directly identify what to adjust including:

Sleep and wake detection, naps detection, real sleep, sleep debt, time to fall asleep function, chronotype, sleep stages monitoring, circadian rhythm, disturbances, SpO2, heart rate, heart rate variability, temperature variation, breathing rate, and sleep quality score©.

Sleep graphs: Provides in-depth insights about your sleep metrics. You can compare your own long-term and short-term trends you need to make changes.

2. Exercise Function

Circular keeps track of your daily activities and fitness goals.

This allows you to visualize and measure your trends and progress, and benefit from personalized data to improve your daily performance over the long term.

Exercise Analytics

Activity metrics: Quantify each component of your physical activity and exercise including:

Automatic activity recognition, activity intensities plus volumes, steps counter, walking equivalency, calories burned, temperature, cardio points, VO2 max, recovery, and heart training zone.

Activity graphs: In-depth information about numerous metrics for you to quantify your current performance and compare it to your own short-term and long-term trends to get to track your progress.

3. Health Function

The Circular Ring continuously monitors your bio-signals and alerts you if anything is unusual.

With it, you can check on your immune system readiness with proactive monitoring.

This allows you to better understand the effect of your lifestyle and environment on your general health.

You can also leverage the power of your ring’s vibrations using a variety of the same guided breathing exercises used by Olympic athletes, yoga masters, and special forces to help you go to sleep, recover, and calm your mind.

This allows you to improve your mental health and focus.

Health Analytics

Wellness metrics: Allows you to track your wellness functions including:

Heart rate variability, body recovery, resting heart rate, sleep balance, temperature variation, breathing rate, heart rate, SpO2, and energy score©.

Energy score: This score reflects your energy level for the day based on your sleep and activity data. Get to know when you can push yourself to max out your daily performances or when its time to take it easy.

Wellness graphs: You can compare your wellness metrics to your own short-term and long-term trends and get to understand the impact of your lifestyle on your well-being in order to improve it.
