Nomicho: Alcohol & BAC Tracker
Drink Diary, Hangover Forecast
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Log a drink in as little as two taps. Watch your estimated blood alcohol concentration (BAC) and state in real time as you drink. See everything you've logged and past sessions as a journal. View deep insights into your patterns.
Most drinking apps assume you want to cut down or quit. Nomicho is the opposite. It never nudges you to drink less, never scolds you, and never grades you. It is a warm and curious record of your own drinking to better understand yourself.
Made by a fellow drinker, for people who enjoy drinking. Originally built in Japan and now adapted to you, wherever you are.
■ Record
Two taps log what you actually drink. Over 100 drinks are built in and curated per country: from sake and lemon sours in Japan to light beers and cocktails from around the world. Sizes and ABV come filled in and editable.
- Create your own drinks. Make it once, one tap after that.
- Nomicho learns your usuals and floats them to the top.
- Edit any drink later: volume, ABV, drink time, how long it took.
- Capture how you felt with hand-drawn illustrations.
- Keep photos of your drinks and sessions in a private library.
- Tag where you drink, by hand or automatically.
- Scan the barcode on cans and bottles. Products outside the catalog are automatically looked up for you.
- Traveling? Switch countries and the drinks, sizes and barcode scanning follow.
- Optionally add drinks, calories, sugars to Apple Health.
■ Predict
See your estimated BAC and how your state shifts in real time as you drink. The model accounts for meal timing, when you finish each glass, and individual factors: sex, weight, height, how easily you flush, how often you drink. Connect Apple Health to fill your profile in a tap. Built on established peer reviewed research.
- Log meals and snacks and the curve adjusts, showing how food lowers your estimate.
- Set a ceiling for the session, like feeling it or buzzed, and see whether another drink would put you over it.
- As your state climbs, Nomicho asks how you feel, so you can watch prediction and reality diverge.
- A hangover forecast, optionally sharpened by sleep and rest from Apple Health. Tell Nomicho how strong a hangover was and it learns.
- A cautious read of how long your estimate is likely to stay above zero.
- Follow your estimate and session from the Lock Screen, the Dynamic Island and Home Screen using Live Activity and Widgets, without having to open the app.
■ Reflect
Keep a journal of your drinking and sessions. Browse past sessions on a calendar and view details on any day. Session recaps map and trace where the night went. A photo library to capture your moments and drinks. And 18 insight cards surface your own patterns.
- A heatmap of when you drink, night-by-night curves, the rhythm of your hours.
- How each drink relates to how you feel, and your pure alcohol totals.
- Your favorites, how the seasons shift your glass, where you tend to end up.
- Calories and sugar over time, completely optional.
- Build your own cards (Plus): use what you've logged and pick what to measure, how to split it, how to draw it.
■ Collect
Every drink you log unlocks an illustrated card, building a collection of what you have actually tried. Browse by category, country, or region and hunt for rare and unique drinks in a carefully curated catalog.
■ Privacy
Nomicho is local-first. Almost everything works without an account or network connection. Easily export all of your data as JSON whenever you like. No ads and no behavioral tracking, ever. Delete your account and all data easily with a few taps in the app.
■ Nomicho Plus
The core features are always free. Plus opens up:
- Your full calendar history.
- All 18 insight cards, plus custom cards of your own.
- Sync across multiple devices.
- Photo backup.
For people of legal drinking age. Nomicho is a tool for recording and reflection, not a medical product or measuring device. Do not use it for medical or legal decisions, or determining if you're fit to drive.

App release and localization for the United States!
New Features
- Travel Mode. Away from home? Switch Nomicho to the country you're in and the preset drinks, drink sizes and barcode scanning follow you, while your plan, your standard drink and your history stay put.
- The the log sheet now has a search function.
- New cards for your Collection: margarita, espresso martini, mimosa and more, collectible wherever you drink them.
Improvements
- Drink timing now defaults to Estimate, which spreads each drink over an estimated drinking time instead of counting it the moment you log it. Settings, Drink timing switches it back.
- Turning on location now maps a session's route by default, recorded only while Nomicho is open.
- Drink photos are now used as icons by default, and AI recaps are now off by default. Both are in Settings.
- Home Screen widgets now match the Live Activity's layout and colours.
- The Nomicho Guide in Settings has been rewritten and updated to match the current screens.
- Assorted bug fixes and polish.
