How it Works
A tiny sensor placed under your sheet tracks your nighttime habits and sends data to an app that reports how well you slept and offers advice and tips from experts.

"I have to wake up at 3:30 a.m., but I go to bed late, so I average only three hours of rest. The app lets you set a sleep goal. I set mine for six hours. I was surprised to learn I typically fell asleep in less than eight minutes but woke three to four times during the night. I like being aware of my habits and knowing where I can improve."
