Read full description

Build a dry-day streak on the calendar, log every drink in seconds, and keep a clear record of how you drink. Wondering when last night's drinks may clear? Alc.Note is an alcohol tracker and drink log that turns your drinks, ABV, body weight, and drinking time into a sober-time estimate. Track pure alcohol, dry days, sleep, stress, and long-term drinking patterns without guilt. ■ What You Can Do with Alc.Note Quick Drink Logging Pick Beer, Highball, Wine, or another drink. Typical volume and ABV are filled in automatically, so each log takes fewer taps. Pure Alcohol Calculation See grams of pure alcohol instead of only counting drinks. Clear colors and meters help you notice when today is moderate, heavy, or above your usual range. Dry-Day Calendar View drink days, lighter days, and dry days on a simple calendar. Spot monthly patterns and the weekdays when you tend to drink more. Sober-Time Estimate "When will it clear?" Based on your body weight and intake, Alc.Note estimates when alcohol may clear from your system. Use it as a reference for planning tomorrow, not as a driving decision. Sleep and Stress Reflection Connect Apple Health sleep data and compare your own records across drink days and dry days. Alc.Note shows trends from your logs, not medical conclusions. ■ Pro Features Sleep x Alcohol Comparison Compare sleep time and condition on drink days vs. dry days, based on your own records. *Yesterday's analysis is available for free. Long-Term Trends Review monthly alcohol intake, dry-day rhythm, spending estimates, and longer patterns over time. CSV/PDF Export Export your logs as CSV or PDF reports for personal review or to prepare for a health checkup conversation. ■ Recommended For • People who want to cut back on drinking • People trying to build dry days • Anyone who wants to understand pure alcohol intake • People reviewing hangovers and drinking habits • Apple Watch users who track sleep • Anyone who wants a calm alcohol journal without ad-heavy clutter Disclaimer The sober-time estimate in this app is a theoretical estimate based on the Widmark formula. It does not accurately reflect individual metabolism or physical condition. Never use the displayed time as a basis for driving or operating machinery.
