The Droidalyzer

The Droidalyzer is an open source, Bluetooth alcohol detector accessory for Android Phones which can be purchased at http://droidalyzer.com. After pairing the device to your phone using Bluetooth, breathe into the device's alcohol sensor and then check your alcohol level from your phone.

The Droidalyzer is a novelty device for entertainment purposes only and is not a professional Breathalyzer.

After each alcohol reading, you’re prompted with various options such as calling a preset designated driver, calling a taxi, finding nearby friends and places (using Facebook integration), and even a random drunk dial option if you’re feeling adventurous. It does not output a blood alcohol content (BAC) reading and instead plays different audio responses relative to alcohol levels with four character voices to choose from.

If you don't have the device, you can still install the app to see how it works by going into settings and turning on simulation mode. Of course it will not detect any actual alcohol without the Droidalyzer hardware.
