BreathalEYES uses iPhone camera to measure Blood Alcohol Content (BAC)

Talk about a useful app for the New Year’s Eve – BreathalEYES will use the iPhone’s built-in camera to measure your (or your buddies’) Blood Alcohol Content (BAC). The software looks for the presence of Horizontal Gaze Nystagmus (HGN) in the eye to do its magic, returning accurate results between BAC 0.02%-0.17%.
As I don’t have an iPhone I haven’t tried this myself (hopefully an Android version will be released soon), but since it costs only a buck (99 cents) there’s only so much to lose and much more to gain. What’s more, this must-have application will work even in low-light conditions (like a bar), though for best results it is suggested there’s a ton of light in the room (or wherever you happen to be when testing BreathalEYES).
Internet connection isn’t needed and since the app doesn’t communicate with the developer’s servers, your privacy is guaranteed… Love the idea and I’m sure you’ll love it too. Check out a short video demoing BreathalEYES in action!
