Short summary : Your blood alcohol estimate on your wrist, at a glance — Widmark formula, 100% on-device. Full description : AlcoCalc estimates your blood alcohol concentration, in g/L, right on your Garmin watch. The calculation uses the Widmark formula, tuned to the weight and gender from your Garmin profile — nothing to set up. The idea: a simple, fast, readable tool to keep an eye on your night out. You log what you drink, AlcoCalc handles the rest. ▸ ADD A DRINK IN A FEW TAPS Pick the type: beer, wine, shot, spirit, or custom. Set the volume (cl) and the alcohol strength (%). Say when you had it: now, 10 min ago, 30 min, 1 h… — handy for logging after the fact. ▸ TRACK IT LIVE Your estimated level shown large, with a color that shifts as the level changes. "Back to 0 at 11:40 PM": the estimated time your level returns to zero. Your session drink count, always in view. ▸ VISUALIZE AND COMPARE A clear curve of your estimated blood alcohol over the last 12 hours. A history of your daily peaks, day by day. Your all-time record, kept for you. ▸ INSTANT GLANCE A read-only preview in the widget list: your estimated level and drink count, without even opening the app. ▸ BUILT FOR THE WATCH Smooth swiping between pages, tap to add, button to adjust. Bilingual: English or French, based on your watch's language. Fully self-contained: everything is calculated and stored on the watch. No account, no connection, no data sent anywhere. IMPORTANT DISCLAIMER — PLEASE READ AlcoCalc provides a rough ESTIMATE only, for fun and personal use. It is NOT a breathalyzer and is in NO WAY a substitute for an official measurement. Your real level depends on many factors the app cannot know (metabolism, tiredness, food, medication, health, hydration…). Do not make any decision based on this app. When in doubt, refrain. The author accepts no liability for how it is used.
