Alc.Note - Drink Log & Sober
Sober time, dry days & liver
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Drank a bit much? First, see when it clears. A no-guilt journal that helps you cut back at your own pace — pure alcohol, dry days, and how it shows up in your sleep.
How much of last night's drinks will clear by tomorrow morning?
Alc.Note is a drinking log that turns your intake, ABV, and time into an estimate of when alcohol clears your system.
Keep the morning-after worry, your dry days, and your drinking habits in check — simply.
■ What you can do with Alc.Note
Intuitive Smart Logging
Just tap icons like Beer, Highball, or Wine. ABV and volume are auto-filled. Log your drink in just 3 seconds, even when you're tipsy.
Pure Alcohol Calculation
Visualize "grams of pure alcohol" instead of just "number of drinks." Based on health guidelines, the app uses colors and meters to alert you in 4 stages: Moderate, Warning, Heavy Drinking, and Danger.
Ring-Style Heatmap Calendar
View your monthly health status at a glance. Red rings for heavy drinking days, Green for moderate, and Indigo for dry days. The game-like visual encourages you to keep your rings healthy.
Sober Prediction (Widmark Formula)
"When will I be sober?"
Based on your weight and intake, the app calculates and displays the estimated time until alcohol leaves your system. Perfect for planning your next day.
■ Pro Features: Invest in Your Health
Unlock advanced features for the price of one premium beer per month.
Sleep x Alcohol Correlation Report
Integrates with iOS HealthKit to analyze "Sleep Quality" on drinking days vs. dry days. Visualize how alcohol affects your rest and improve your habits.
*Yesterday's analysis is available for free.
Unlimited Long-term Analysis
Graph your data over any period. Track monthly trends in alcohol intake and spending.
Data Export (CSV/PDF)
Export your logs to CSV or PDF reports. Ideal for sharing with doctors during checkups or for your own detailed analysis.

■ Developer's Note

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
We rebuilt the first-run experience to be gentler and made the “when it clears” estimate easier to read. Logging and insights got some polish too.
We’ll keep helping you change how you drink, without the guilt.
