drinkYs - BAC & Drink Tracker — App Store rankings

About this app

The developer's US App Store description, in full.

drinkYs calculates your blood alcohol content with a minute-by-minute simulation, not a rough estimate. Track drinks, see your BAC curve live, and know exactly when you'll be sober. Built on peer-reviewed pharmacokinetic research. Your data never leaves your device. ONE-TAP LOGGING WITH PARTIAL DRINKS Tap to log your default drink instantly. Long-press to pick from your custom drink types. Log partial drinks too — half a pint, a small measure, or any fractional amount — for precise, accurate tracking. LIVE BAC CURVES Watch your blood alcohol rise and fall on real-time charts — 2-hour window and full 24-hour view. The simulation accounts for absorption, elimination, and your body profile. SOBER-BY ESTIMATE See exactly when you'll drop below your chosen threshold — even accounting for drinks still being absorbed. PERSONALISED TO YOU Enter your weight, sex, and drinking experience. Your elimination rate is calculated automatically using the Widmark formula. APPLE HEALTH INTEGRATION drinkYs writes your blood alcohol estimates to the Apple Health app so you can track them alongside your other health data. Requires permission — your data stays on your device and is never shared with us or any third party. FULL HISTORY & HEATMAPS Browse every drink grouped by day. Edit timestamps, change drink types, or export to CSV. Monthly calendar heatmap shows your patterns in Drinks, Units, or BAC mode. PREMIUM — ONE-TIME PURCHASE Unlock body profile customisation, all drink type slots with custom volumes and ABV, stats sharing, and full app preferences. Pay once — no subscription. SCIENCE-BASED, PRIVATELY STORED Calculations use the Widmark formula and peer-reviewed research. No account, no cloud, no analytics. Everything stays on your iPhone. drinkYs provides estimates for informational purposes only. BAC estimates are not a substitute for certified testing. Never use this app to determine whether you are safe to drive. Always choose a safe way home.
