Proof claims that the enzyme-based electrochemical sensor integrated within is able to convert alcohol into an electrical current. Through this particular principle, it can then provide a fairly accurate readout on your current blood alcohol content (BAC) level discreetly, via an Android or iOS app. It does sound like a good idea, but what happens when you go over your alcohol limit and are too drunk to figure out why your smartphone keeps on sending you updates at regular intervals with ever increasing numbers? It is not as though Proof is hooked up to the establishment that you are in, informing the bartender not to serve you any more drinks.
This makes Proof more of a fun gadget than anything else, as it is also able to predict just how drunk you will end up later at night — or the next morning, based on your current drinking pattern and rate. It will also provide a prediction on the moment when your body ends up sober. At the end of the day, Proof is meant to empower regular folks to be able to make an educated decision concerning alcohol.
Milo Sensors hopes to roll out Proof through a crowdfunding campaign, targeting a sticker price of $100 to $150 for it.
