The world’s first smart ring specifically designed for single-handed sports and fitness use was launched at digital CES in January and digital ISPO in February 2021. Developed by ArcX Technology, a UK-based sport tech start-up, the ring is designed to be worn on the index finger and controlled with the thumb.  Connected via Bluetooth to any smartphone, the ring allows users to store phones in a pocket or backpack, controlling playlists and other phone functions simply and easily, even when wearing gloves.
