Café Amazon in Thailand created a very useful app with social responsibility while still finding a way to push product. The best part is, they did it in a way that doesn’t feel forced or trite.

It’s pretty simple:
Launch the app and mount your phone on the windshield
It uses facial recognition to scan for eye fatigue
If a driver’s eyes shut for a moment the app sounds an alarm, waking the driver
It then directs you to the nearest Café Amazon for caffeine fix

It’s simple and brilliant.
