Alcohol Diary turns every drink you log into grams of pure alcohol.
See how much you drank today and this week, and whether you're keeping alcohol-free days — in numbers and colors, at a glance. It's for anyone who wants to see their drinking clearly and find their own pace.
■ Log with one tap
・Common drinks are ready from the start: 12 oz beer, US and UK pints, hard seltzer, a 5 oz glass of wine, a 1.5 oz shot, mixed drinks and more
・Tap to log one drink; press and hold to change the amount, the number of drinks (in steps of 0.5) or the time
・Save your own drinks with their own volume and ABV
■ Today and this week
・Today's pure alcohol in big numbers
・A bar shows what's left of your weekly limit
・Drinks after midnight count toward the previous day until 5 AM (you can change this)
■ Rough estimate of when alcohol clears
・Enter your weight to see "~2 h 50 min left, around 12:56 AM"
・Uses the common rule of thumb of about 0.1 g per kg of body weight per hour. It is only a rough estimate and varies a lot with your body, health and sleep. Never use it to decide whether you can drive
■ Look back with the calendar
・Each day is colored: none / under 20 g / under 40 g / 40 g or more
・Tap a date to see, edit or add entries
■ Widgets
・Today's total and what's left this week on the Home Screen and Lock Screen
・Log "+1" straight from the widget

・Export your entries as CSV
■ English and Japanese
Switch the language any time in Settings → 言語 / Language.
■ How the numbers work
Pure alcohol (g) = volume (ml) × ABV (%) ÷ 100 × 0.8. The default weekly limit (280 g for men, 140 g for women) comes from the 2024 drinking guideline of Japan's Ministry of Health, Labour and Welfare. Guidelines differ by country, so you can set your own limit in Settings.
■ Please note
・This app does not give medical advice or diagnoses. If you are worried about your health or your drinking, talk to a doctor.
・Only drink if you are of legal drinking age where you live.
・Never drink and drive.
■ Your entries stay on your iPhone
No account needed. Your entries are stored only on your iPhone and are never sent to our servers.
