DrinkTracker
$1.99, slappme.com
This simulated breathalyzer bases its calculation of blood alcohol content on your age, gender, height, weight and real-time bar tab. It updates your BAC every minute and touts a countdown for when you’re safe to drive. It also finds nearby taxis. And Version 3, dropping in November, has a bizarre auto-tweet feature so you can let friends know when you’re drinking.

Cops use platinum-grade fuel cell sensors in their breathalyzers, and so does this device. It plugs into your smartphone and tracks intoxication so you’ll know exactly how many Long Island Iced Teas make you dangerous. It’s also equipped to call cabs and find nearby restaurants for sobering up.
BACtrack
$149, bactrack.com
The Cadillac of smartphone breathalyzers uses a fuel cell sensor and internal breath pump to ensure the “gold standard” of accuracy. It tracks BAC and puts it in context (0.03: “You may be experiencing a loss of shyness and slight euphoria”), graphs your drinking habits and calculates time till you’re sober again. On the social side, it’s also a photo-driven drink diary, and shows the last 100 test results made public in your region. That’s one fancy drunk map.
