It didn't matter where I put my phone, I received the audio alert of "You're eyes are detected," followed immediately by "you're eyes are not detected." The app then shows a map, and you have to concentrate on the device instead of the road in order to reset the app.

Difficult to work with and unreliable

Was interested in this app but when I tried it out in my house, had the phone 10" from my face it would immediately squawk at me and try to find a coffee shop at which time it said no shops were found in my country. Is this a European app or something? And who would place their phone on the windshield directly in front of them while they're driving like the app suggests? Pretty stupid app.

Horrible app. It does not work at all when drivers are usually drowsy...at night! During the day if you look away at the phone to make a turn it starts yelling at you and scares you. Terrible marketing idea from a coffee company I have never heard of. But I will now associate them with this terrible app.
