A Fitbit the size of a ring is surprisingly wonderful

It’s essentially a device that has all of the accelerometer and heart-rate sensing technology you’ll find in a Fitbit, miniaturized down to a sleek titanium ring that could pass for a wedding band. This tiny, downright elegant marvel of technology–powered by a battery so small it hadn’t been invented before the project began–makes the breakthrough curved batteries inside the Fuelband look like medieval iron cuffs.

Ultimately, I still don’t really believe in data tracking for data tracking’s sake. But wearing the Motiv for a week, I got a taste of the wearable future to come–a future that won’t be defined by blinky, distracting gadgets like the Apple Watch, but technology that’s subtly woven into the fabric of our lives–and our clothes. fastcodesign.com
