DrinkTracker Breathalyzer (S$2.58)
Avoid incurring the wrath of the folks manning the early morning roadblocks, breathalyze yourself before they can get to you. While this doesn’t turn your phone into a full-fledged breathalyzer that you can exhale your alcohol-soaked breath into, you can key in the type and quantity of alcohol you’re drinking and it’ll work out your BAC (blood alcohol content) according to your profile. You just have to stay sober enough to keep up the data entry.
Replaces: That super-cautious and paranoid friend who keeps asking if you’ve had enough.
