There are plenty of apps out there designed to tell you about your sleeping habits. Unfortunately, most of them don't work all that well and require your phone on the mattress besides you — which just makes me feel attached to my phone in a way that makes me cringe.

Aura is made up of a sleep sensor that slips underneath your mattress, syncing with a device that sits on your nightstand. Together, the two gadgets record and monitor a variety of factors to give a better understanding of your sleeping patterns. The sensor focuses on your physical patterns (like your movements, breathing cycles, and your heart rate), while the bedside unit takes note of the environment (including noise pollution, temperature, and light levels).
