According to market research company IDC, in 2025, the output of smart rings increased by 49% compared to the previous year. Meanwhile, smartwatches only grew by 6%.
Once considered a product for the niche market, smart rings are increasingly favored by consumers recently, providing useful information about sleep and health similar to smartwatches but with a more discreet design.
Most modern smart rings can track sleep, activity and heart rate with lighter hardware and, for most users, less uncomfortable than smartwatches.
They also often have longer battery life and give more accurate measurement results. This is because the skin on the finger is thinner than the skin on the wrist, and the sensors of the smart ring are placed near important arteries.
According to IDC, many consumers have chosen to wear both devices. In which, smartwatches are used to track sports activities and receive notifications, while smartwatches are used to monitor continuously day and night. Although the growth rate is slower, IDC estimates that 163.5 million smartwatches were produced in 2025, compared to about 4.3 million smartwatches.
Currently, the smart ring market is a fierce race between many major brands. Oura Health Oy of Finland launched smart rings in 2015. This company is valued at over 11 billion USD and in 2025, Oura's revenue is estimated at over 1 billion USD.
In addition, Samsung's Galaxy Ring, launched in 2024 and using artificial intelligence (AI) to provide detailed health reports, including indicators such as sleep, activity, heart rate and heart rate variability.
This smart ring also gives advice and recommendations designed to help improve daily health and spirit.
Experts also said that startups and technology giants are expected to introduce new smart ring product models at the CES consumer technology conference taking place this week in Las Vegas, USA.
It's a bit of a bit of a bit of a bit of a bit of a bit.
