How are you sleeping? Not so great? There's a new app called Zeo that's supposed to help with all that. It all starts with a headband. From Reuters: A soft-sensor headband measures brainwave activity, muscle tone and eye movements, the same signals that would be taken by a professional sleep lab, but at a consumer level.
The signals are relayed through Bluetooth to the user's iPhone, iPad, or Android smartphone and uploaded to Zeo's website.
All this data can be used to teach you how to sleep better. Plus, you can synch it with other apps, like RunKeeper, to see how your sleep affects your workouts. The app is consistent with what medical professionals in sleep labs find about 75 percent of the time.
