With its visually-pleasing and engaging interface, this app claims to track blood alcohol readings in real time. One can imagine a group of mates camped at a bar gambling with the alcohol measures to outdo each other in a digital drinking game. It is quite upfront that it is suited for entertainment purposes only rather than offering accurate BAC readings.
The designer is just that, a developer who appears more knowledgeable about algorithms than a trusted expert on alcohol consumption and metabolism rates. On the one hand it promotes its ability to deliver precise calculations while on the other acknowledging its scientific limitations. It is somewhat concerning that some drinkers may pose risks to themselves and other motorists if they rely on its questionable readings as a licence to drive.
