Measuring blood alcohol level might be just as important to some people as measuring steps or heart rate. It’s a relatively new metric in the “quantified self” movement, but it makes sense.

Breathometer today unveiled a new device in its line of breathalyzers — a wearable gadget called the Breeze that can clip onto your clothing or onto the inside of a purse.

It also integrates with Apple’s HealthKit. The idea is that you can carry around the Breeze during a night of drinking and feed the results into the Breathometer app. The data can be shared with HealthKit and directed to display (with other kinds of health data) in the Health app in iOS 8.

Breathometer CEO Charles Michael Yim told me that the device, which communicates via Bluetooth with your phone, returns results very quickly and with law enforcement-grade accuracy. If you’ve had too much to drink, the Breathometer app can even call you an Uber car.

“We set out to create something that’s effortless to carry and use when you’re out with friends so people will actually want to use it,” Yim said. “With its cool wearable design, the all-new app, and superb accuracy, Breeze nails it; we couldn’t be more pleased.”

The Breeze is available online at Breathometer.com and BestBuy.com and will go on sale for $100 at Best Buy stores this holiday season.
