This fitness ring from Motiv, according to TechCrunch, could potentially represent "the beginnings of liberation from the tyranny of the wrist." Although a ring has less room for a battery and nixes a display, the discreet and capable design is still able to carry out the basic functions consumers are looking for in a wearable fitness tracker.
Made out of titanium, the device is lightweight with two sensors: a heart rate monitor and an accelerometer. These enable the fitness ring to monitor the wearer's active and resting heart rate, calories, distance, sleep time and steps. The accompanying Motiv app measures things in active minutes, changing the focus from the distance you have traveled to the amount of time you spend moving.
