Misfit tackled activity tracking with its Shine offering that looks more like a fashion accessory than a sensor. Now, the data gathering outfit is looking to wrangle sleep cycles with the Beddit sleep monitor. Claiming to be the "world's thinnest sleep sensor," the unit resides on your mattress as opposed to being tucked in between the sheets. From there, the gadget keeps an eye on heart rate, movement, snoring and ambient sound in order to gauge the quality of your slumber. Collected info is then beamed to your smartphone of choice for analysis within the Misfit app. If you're looking to quantify those Zs you catch, Beddit is available now for $150 -- half the price of Withings' Aura bedside system, but without the added sound and light show.
