How accurate is the BAC estimate?
Unless you have a method of measuring your BAC over time as you drink and you can calibrate your BAC to the estimate provided by Drink Logger, you should assume that the estimated BAC is not accurate. It is only an estimate. How accurate it is will depend on the physiology of the person drinking, how accurately the alcohol content and amount of the consumed drinks is known, as well as environmental factors. As it is nearly impossible to know these additional factors with any certainty, it is also impossible to know how the accuracy the computed BAC. For your own safety and for the safety of others, you should not assume that the estimated BAC is accurate.
