Summary: Alcohoot, a smartphone-powered breathalyzer, is now available to help you gauge your BAC and slow you down before things get out of hand. Alcohoot, shipping now for $119, is more expensive than most other smartphone breathalyzers on the market – the Breathometer, for example, only costs $49. But Alcohoot features "police-grade accuracy" and plugs directly into your handset's headphone jack, making it more accurate and more convenient than most competing products. To preserve the device’s accuracy, Alcohoot encourages you to keep up with the required annual calibration; each year, you’ll get a new device along with a shipping label to return your current one for a $30 fee. Alcohoot works on both Android and iOS, and its bundled companion app shows restaurants within walking distance, a link to Uber and even a tool to track your consumption throughout the night. So the next time you go out to dinner and have a few drinks, remember to pull out your smartphone before getting behind the wheel.
