Sober O'Clock: BAC Calculator

Know your estimated BAC before the next round. Sober O'Clock is a BAC calculator and drink tracker. It turns the drinks you log into a live blood alcohol estimate, shown as a min–max range with an estimated sober time, and it previews how one more drink would change your evening. It is an estimate, not a breathalyzer. The result depends on what and when you drink, your body and whether you have eaten. It cannot tell you how you feel or whether you are fit to drive. Never drink and drive. Leave the keys at home, plan your ride home, and when in doubt, don't drive. KEY FEATURES • Drink log with 42 drinks: beers, wines, shots, spirits, cocktails and cider. Add favourites, recent drinks or your own custom drink in one tap. • Live blood alcohol estimate in ‰ with a min–max band, so you see the range, not just one number. • Sober time: the estimated time your level returns to zero, with a latest time. • "One more?" preview: see how the next drink changes your curve and your sober time before you order. • Stomach setting: empty, normal or after a meal, because food slows how fast alcohol is absorbed. • Optional height and age for the Watson or Seidl formula. Otherwise the Widmark formula is used. • Legal limits for 50+ countries, including Poland's two tiers and zero-tolerance countries. Limits change, so check your local rules. • Evening history: each night's curve and a morning summary. • Home-screen widgets in 2×2 and 4×2 sizes. • kg or lb, dark, light or system theme, 10 languages. WHO IT IS FOR • Friends planning a night out who want to keep track. • Anyone curious how drinks add up over an evening. • People who want to review their history and spot patterns. FREE Sober O'Clock is free. Ads appear only as a small banner on the settings screen. RESPONSIBLE DRINKING Sober O'Clock gives estimates based on the details you enter. It is not a medical device and does not measure your blood. Alcohol affects everyone differently. Never drink and drive. If you have health questions, talk to a doctor.
