LISTERINE® Smile Detector


Description of App: 

Never miss a smile. LISTERINE® Smile Detector uses your camera to detect when someone is smiling at you, so even if you can’t see a smile – there’s another way so you can still feel one.

Simply direct your camera towards those around you and the app will vibrate or make a sound when you are being smiled at.

Tested by the RNIB (Royal National Institute of Blind People).

LISTERINE® believes in the power of every smile.

How it works:

Just download the app and open it up. Choose the front or rear facing camera on your phone and point it at someone to be notified when they smile. The app will also play a sound when it detects a smile, but if a vibrate is enough you can mute it by clicking on the settings icon.
