There’s nothing worse on a road trip than battling the ZZZ’s while driving (except maybe a jack rabbit destroying your vehicle), so a chain of coffee shops has created an app called Drive Awake that tracks a drivers’ drowsiness and directs them to the closest coffee shop whenever they nod off.
Drive Awake works by using the iPhone’s front-facing camera to monitor a drivers eyes. You simply mount your iPhone to your windshield and it tracks your retinas to see if they’re open. Once the app determines you’re falling asleep it emits a loud and annoying parrot squawk to get your attention and help you find some coffee.
Here’s a video of the app in action:
