From a Finnish team who've been engineering sleep stat-trackers for sleep clinics since 2006, Beddit's a new civilian model that takes readings via an ultra thin film sensor you strap under your bedsheet. Based on ballistogardiography — a scientific method for measuring cardiorespiratory functions
while attempting to pronounce really long and ridiculous words — it captures tiny movements caused by both your breathing and heartbeat. In the morning, data's sent via Bluetooth to your phone, and you're given a visual breakdown of your shuteye behavior in a dedicated app (e.g., when you entered deep sleep, when/if you were snoring, and any moments of particularly unusual activity). Then, it turns that data into actionable ideas to improve sleep and wellness, though you hopefully don't need an app to tell you that gorging on Chinese takeout after 11 p.m. is a mistake.
