Macsoftex today announces iAlcohol 1.1, an update to their blood alcohol content app for iPhone and iPod touch. Intuitively easy to use, iAlcohol determines the level of alcohol in a persons blood and calculates the required break in driving. The formula calculates the influence of factors on the duration of the phases of alcohol intoxication, providing 90% accuracy. The application will help you choose a suitable drink and the amount you are allowed to consume within this interval of time.
