bioring the personal trainer on your finger 2 - Circular Smart Ring: a fashionable, feature-rich health assistant

Smart rings are yet to take off in any meaningful way but we are told the finger is a great place to track a range of physiological metrics. One of the most popular such devices is the Oura ring. It puts a lot of emphasis on analyzing the quality of your rest but also tracks some activity during the day. Now we have an even more complete solution in the making.

It is called Circular. The smart ring comes with a 3-axis accelerometer and infrared heart rate sensor that allow it to track a range of metrics. At night this includes circadian rhythm, sleep, heart rate & heart rate variability, blood oxygen levels and more. During the day this also includes activity volumes with automatic recognition, steps, energy levels and more.

The Circular ring connects via Bluetooth to your iPhone or Android device. If your smartphone is not close by, it can store detailed data for up to 7 days.

Outside of wellness, the ring dishes out notifications through vibrations, it has smart controls and intelligent alarms. The accompanying smartphone app comes with a personal assistant called Kira which delivers personal insights rather than just metrics and raw data.

“A lot of the wearable devices that we see are too bulky, too gadget looking, lack personalization and present users with raw data without telling them how to use it. As wearable users ourselves, we wanted a device that would not only be more personal but would also use the data it found to help make recommendations for an overall healthier lifestyle,” says Circular’s CEO Amaury Kosman.

Built to last, the scratch and water-resistant device comes with an interchangeable shell so you can tailor it to your liking. At the outset there will be a Silver, Black Fit and Rose Gold shell to swap between. The body is made of nickel-free clinical plastic.

The thing is designed to fit in seamlessly with your life so there is no on/off button. The ring knows when you’re wearing it and it will automatically put itself into sleep mode when possible. Having said that, there is a physical push button which is used as a shortcut to things you do most. Battery life is a decent 2 days on a quick 60 minute charge.

On paper, this certainly sounds like a useful little health-assistant. The popularity of Oura shows there is lots of demand for such devices. If all goes well with production, a $220 pledge see a Circular Smart Ring delivered to your doorstep in August.
