Data nerds who also enjoy an occasional pint of ale will rejoice in discovering the BACtrack Mobile Breathalyzer. It goes a few steps beyond your traditional portable breathalyzer by integrating some pretty solid social features, as well as playing nice with your smartphone. It accurately tracks your blood alcohol level (by using the more professional fuel-cell technology, rather than cheaper semiconductors) and plots it on a graph over time. You can see how drunk you’re getting, how fast and more importantly, when you’ll be back to an acceptable level for driving. Take pictures of your drinks, and a personal drinking diary lets you take notes of each as you go along. And if you’re in the mood of sharing, you can set four levels of privacy, from private and personal, to fully social. You can also pick an intermediary step for alerting only a designated driver, and another for sharing, but anonymously. Sadly, the BACtrack Mobile Breathalyzer only works with iDevices, but at $150, we think is reasonably priced given the feature set.
