We鈥檝e covered a lot of breathalyzergadgets to keep you in check at happy hour, and as pumped as we鈥檝e been about all of the technology, everything we鈥檝e covered so far has had to plug into your phone for power. But not anymore. The BAM from Lapka is so futuristic, it barely needs power.


The BAM (Breath Alcohol Monitor) doesn鈥檛 have wires or batteries. You just hold it up to your mouth and blow, and it automatically calibrates your blood alcohol level with your phone. And you only have to charge it once every few months. Seriously.


You can feel free to share the BAM with friends and just use your hand as a mouthpiece to prevent germ spreading, making all of your friends healthier and safer on many levels.


The device is discrete, comes on a rope chain and makes you look like you鈥檙e just accessorizing like a badass.


The app is full of real talk; it鈥檚 not going to sugarcoat where you are with things. It even gives you an approximated number of hours that you鈥檒l need for your body to burn off however much alcohol is currently inside of you.


So how does this modern marvel work? It runs on an electrochemical platinum fuel cell sensor to give you tip-top precision with each reading. The app just starts up when you breathe into the device.


Got an Apple Watch? Soon you鈥檒l be able to get your readings there too. On the watch or on your phone, you can track your alcohol levels throughout the night, and, if you feel like reliving things the next day, look back at the stats and see how your evening played out.


Staying safe has never been such cinch. The Lapka isn鈥檛 available quite yet, but when it is, it鈥檒l be $99. Stay up-to-date on the latest news on Lapka鈥檚 Twitter.
