Smart rings are in the nascent stage right now in the wearable market segment. One startup that makes such smart rings is Finland-based Oura and it has been quite successful in the same. Founded in 2013 by Kari Kivelä, Markku Koskela, and Petteri Lahtela, this startup develops Oura Ring wearable hardware.
The Oura Ring is sleek and is fitted with sensors so that it can measure users’ sleep patterns, track their activity, and measure their body temperature. It won’t be an exaggeration to say that it is one of the potentially game-changing wearables in the market right now.
