The Good The Breathometer's app interface makes it easy to start testing for blood-alcohol content. The color-coded graphic results also show at what time sobriety will be attained.
The Bad The design of the device allows for mistesting and germ-sharing. The app does not let you share results on social networks.
The Bottom Line The Breathometer makes for a fun party game and a potential way to meet people in bars, but its testing results should not be taken as proof of driver safety.
iPhone breathalyzer fun, but prone to mistesting
The police use breathalyzers to test drivers' sobriety, so why shouldn't you have the same capability? That's the thinking behind the Breathometer, a personal breathalyzer device that determines your blood-alcohol level, showing if it's safe and legal to get behind the wheel after a night spent staring at rows of half empty bottles behind a bar or confessing your deepest desires to just-met strangers.
Actually, personal breathalyzers are not uncommon -- during a quick search on Amazon I found a variety, ranging from keyring-size to handheld models similar to the kind the police use. Breathometer's gimmick is that it turns your iPhone into a breathalyzer, putting a high-tech spin on drunkenness.
The Breathometer device is small, about the size of an airplane bottle, making it easy to carry around in a pocket. A flap conceals a AAA battery, which provides enough power for 250 tests, according to the company's Web site. A hole through one corner makes it possible to attach a keychain. Another hole, near the opposite corner, glows like a bottle of Blue Curacao when the device is on. That's the breathalyzer part, where you blow out your rum-soaked breath and broken dreams.
