Alcootest is a utility application designed to provide users with a calculated estimate of their blood alcohol content (BAC). It functions by processing user-inputted personal metrics alongside details of alcohol consumption to generate a projected BAC level. The primary stated objective is to offer data that can inform personal decisions regarding activities like driving, though it positions itself strictly as an informational aid rather than a certified measuring device. The interface is structured to present this calculation and subsequent time-to-sober estimates in a straightforward, tabular format.
The application's central engine is based on the Widmark formula, a recognized pharmacokinetic model for estimating alcohol distribution. Users are required to input specific biological parameters—including weight, gender, and height—which the algorithm uses to approximate total body water. This data is then cross-referenced with the declared alcohol intake, where the user specifies the type and quantity of beverages consumed. The output is a numerical BAC percentage and a dynamically updated countdown timer indicating the projected moment when the BAC is estimated to return to zero. The design avoids superfluous graphics, focusing instead on presenting the numerical data and countdown in a clear, chronological log.
The user experience is deliberately minimalistic. The main screen is dominated by input fields for personal data and a drink logging system, with results displayed in a dedicated panel. A historical log tracks previous sessions. The application supports multiple language options, which extends its utility across different user bases. There are no interstitial advertising units within the core calculation workflow, which contributes to an uninterrupted user task flow. The presentation of information is systematic, with color-coding or prominent typography used to delineate between input sections, active results, and historical data.
It is critical to note that the calculated BAC is an estimate based on submitted data and standard metabolic averages. It cannot account for individual variations in metabolism, food intake, or medication. The application does not connect to any external hardware and is not calibrated or certified as a forensic tool. Its value lies in providing a consistent, personalized reference point based on the inputs given.
