Big tech companies are working on smart rings. But when smart watches and phones are so good, what’s the point of smart jewellery?

Digital health tracking tech is everywhere. There are monitors to measure your heart rate as you work out, smartwatches to tell you how many steps you take each day and smartphone apps to chart your dietary habits. But with so much health data already at our fingertips, do we really need another type of device keeping tabs on us? The big tech companies seem to think so, hence the rise of smart rings.

Great for simplicity and battery life

This is the big selling point of smart rings. While some smartwatches – the Garmin Fenix 7, for example – can last for weeks, the most common devices (those from Samsung and Apple) require much more frequent recharging. The longevity of smart rings comes down to their simplicity.

Smartwatches are designed to be do-it-all products and need a battery capable of handling a constant barrage of tasks. Smart rings, in contrast, do much less.
