So one of the apps that I want to create is a breathalyzer app. Unfortunately, BACtrack beat me to it. The website, linked above, makes testing your Blood Alcohol Content (BAC) effortless. BACtrack enables you to do this by blowing into your choice of about 3 different devices that link to an app on your respective Smart phone. The website states that in some cases you don’t even need to take your phone out. How great! I for one don’t drink that much and I must tip my hat to BACtrack for beating me to my great invention. Although the BACtrack Vio has a keychain that works with the app, I wonder will we ever see an attachment for a breathalyzer that plugs into a smartphone?
