Designer Vadik Marmeladov and his team at Lapka have created an inconspicuous breath alcohol monitor that sends its results to the users’ smartphones and also lets them compare their results with friends or share them.

The Lapka Breath Alcohol Monitor is a sleek buttonless ceramic cylinder that contains a police-grade electrochemical fuel cell sensor. It can estimate one’s blood alcohol content and then send the information to the user’s smartphone using sound waves when he or she blows into it.


To use the breath alcohol monitor, users need to hold it in their fist and use the edge of their hand as the mouthpiece. The device doesn’t even need to touch their lips as long as it is cupped properly in one’s hand. Blowing into the device automatically activates the app on the user’s smartphone and provides the estimated blood alcohol content. There’s no need to sync the device with the app every time. Using the unique device ID, it calibrates automatically via Lapka servers.

The app keeps track of the user’s breath alcohol content levels. The app also has a ‘party mode’ that lets users compare their results with friends.

The Lapka Breath Alcohol Monitor is compatible with Android and iOS devices and is available to pre-order. Each breath monitor comes with its own USB charger and neck strap. The product will be released in October.
