" PopMech editors welcome any opportunity to drink for the sake of science. So, after a slew of phone-attachable alcohol monitors hit the market, we decided to find out how two of the top sellers measure up to a police-grade device. Our test drink was 1.5 ounces of 84.8-proof Michter&amp;#039;s Straight Rye Whiskey. Since ignorance of the law is no excuse, we must inform you that a blood alcohol content (BAC) of .08 is the DWI benchmark everywhere in the U.S.    CONTROL: BACTRACK S80 Pro Breathalyzer  REGISTERED BAC AFTER 1 DRINK: .02 REGISTERED BAC AFTER 2 DRINKS: .05 This is the one that Johnny Law uses.    Breathometer PRICE: $49 REGISTERED BAC AFTER 1 DRINK: .02 REGISTERED BAC AFTER 2 DRINKS: .05 The Breathometer requires a log-in that can be frustrating after you&amp;#039;ve had a few and forgotten what password you used the last time you had a few. The app shows only two numbers past the decimal, which is dicey. Of course, if you&amp;#039;re coming that close, you shouldn&amp;#039;t even think of driving. Fortunately, it comes with a Call a Cab feature. It also calculates by what time you&amp;#039;ll be dead sober. If there&amp;#039;s going to be alcohol in your system the next morning, go home\u2014in a cab!    Alcohoot PRICE: $119 REGISTERED BAC AFTER 1 DRINK: .019 REGISTERED BAC AFTER 2 DRINKS: .043 Alcohoot doesn&amp;#039;t require a log-in. And the device has you blow into a tube instead of through a hole. (The Breathometer made us worry if we were doing it right.) The results include an extra decimal and a time graph that demonstrates how quickly you&amp;#039;re getting &amp;quot;turnt up.&amp;quot; When we tapped the Taxi feature we found no links to taxis, just one to the Uber car-service app. But Alcohoot did point us to the nearest open restaurants. That came in handy around pizza o&amp;#039;clock. BOTTOM LINE: Both devices are accurate. Alcohoot was easier to use and had better features, but we&amp;#039;re not sure they justify paying more than twice the price. (Photos by Grant Cornett.) "^^<http://www.w3.org/2001/XMLSchema#string>
