Smart rings are relatively new (the first smart ring of the British company McLear appeared on sale in 2013) and a not so common type of wearable electronics such as fitness bracelets. With the help of smart rings, you can control equipment, store passwords, unlock smartphones, make contactless payments and perform many other actions.

The new "smart" Circular ring performs, first of all, the functions of a fitness bracelet. It collects and analyzes information about the state of the body during the day and issues recommendations for improving well-being. In particular, the gadget will help you learn about the effect of sleep on the user's life and vice versa.

Monitoring data is displayed through a special application on the smartphone. Setting up the gadget is very simple: all software updates are transmitted to it wirelessly.

According to techcult.ru, Circular collects information about the state of the body using two sensors (infrared heart rate sensor and accelerometer). The ring contains an integrated processor that processes the data and sends it via Bluetooth to the mobile application for analysis. The application, in turn, uses machine learning to better understand user habits and offer personalized recommendations.

The sleek Circular casing is made of durable, water-resistant, scratch-resistant material. Charging (for 2 days of use) is carried out within an hour using a special device.

Circular can be ordered on Kickstarter for 179 euros. Worldwide sales should begin in August 2020.
