The next Fitbit wearable could be a ring with many health tracking features

Fitbit has been selling fitness trackers and smartwatches for years, most recently with the Versa 3 and the Sense. The company has pioneered many health features, including measuring blood oxygen saturation (SpO2) levels. Now, TechRadar has discovered a patent that Fitbit filed a patent for a fitness ring.

Published by the United States Patent and Trademark Office (USPTO), Fitbit describes the device as 'a ring for optically measuring biometric data' that can calculate SpO2 values. Theoretically, such a device could be more accurate than a smartwatch, which could be attractive to those who like to track their health statistics.

The patent document describes that the fitness ring can relay data to either a connected smartwatch or a smartphone. Apparently, the ring could do this over Bluetooth or NFC. Updates could be transferred by Bluetooth, too.

Additionally, the document notes that Fitbit could produce several sizes to be worn on different fingers, with a larger ring for your thumb. TechRadar notes that Fitbit initially patented a fitness or smart ring in 2019, so the company could be fairly close to bringing something to market.
