Smart rings are designed to measure sleep quality and keep daily statistics on your overall health. Smart watches already do the same thing.
According to Dr Ian Wei, head of the smart wearable devices research group at Nottingham Trent University, smart rings are pretty much the same thing as smartwatches. They track the same health metrics using the same equipment.
Samsung and Apple are reportedly currently working on smart rings. In addition, some companies already have such devices on sale.
The main advantage of smart rings is ease of use and good battery life. But since the ring is much smaller, it’s harder for it to track as many health metrics as a watch at once. Additionally, it is now difficult for smart rings to track a person’s physical activity; Without a smartphone, they cannot store much data or view information from them.
However, currently smart rings are not much different from smart watches or health tracking devices, but they are very expensive. That is, their functions do not justify their cost.
