Blood alcohol tracker for Android
Log a drink. Watch it rise, then fall.
AlcoTrack is a drink diary that turns what you drank into a live blood alcohol estimate: it climbs while you drink, eases back down at your own pace, and tells you the hour it should be back to zero. Everything you log stays on your phone.

Try the maths
This is the same calculation the app runs: Watson's body-water formula, a linear absorption window per drink, and a steady elimination rate. Tap a few drinks for an evening that starts at 8 pm and see where the estimate lands. Nothing you set here leaves this page or survives a reload.
Age is fixed at 30 here. The app asks for yours.

An estimate, like the app's. Food, medication and your own metabolism move the real number, and none of this says anything about whether you can drive. You can't, after drinking.
All it needs is what you drank
- Tap a drink you saved. Beer, wine, a shot, or one of 80 cocktail recipes. The ones you drink most are one tap, not a form.
- Watch the estimate rise, then fall. The number on the home screen moves with every drink, and a line under it says when it should read zero again.
- Look back over the week. Drinks, grams, the days you skipped, and what it cost, next to the week before.
You enter your weight, height and age once. Biological sex too, or leave it out and the app assumes the more cautious estimate. That is the whole setup.
Count your alcohol-free days
Dry January, Sober October, or a Tuesday you decided to skip: the calendar counts them all the same, and a streak keeps going until you log something. Set a weekly limit or a budget if you want one. If you don't, the calendar still fills in.
A night with no entry can count as sober or as unknown. That is a setting, because people use the diary in both ways, and the app should not guess which one you meant.
What drinking does to your sleep
If a watch writes into Health Connect, AlcoTrack can read the nights back: how long you slept, your resting heart rate, your HRV. It puts the nights you drank next to the nights you didn't, and after a few of each it can say by how much they differ. For you, not for the average person.
Samsung Health, Garmin, Fitbit, Oura, Withings, Polar and the rest already write there. AlcoTrack only reads, writes nothing back, and the whole thing is off until you turn it on.
Ask the AI about your week
The coach has read your log and nothing else. Ask it why last week looked the way it did and it answers from your own numbers, then shows you exactly which ones it used. It is in beta, it can be wrong, and it never lectures.
Your question and the data it needs go to a relay I run, then to the model, and nowhere else: the chat is not stored anywhere and is never used to train anything. Off until you turn it on, and the consent screen says all of this again before the first message.
The rest of it
Favorites and 80 cocktails
Save the drinks you actually order. The cocktail list carries the recipe and the alcohol maths for each one.
A widget on the home screen
Your current estimate and the time it reaches zero, without opening the app.
Hydration reminders
A nudge for a glass of water after every so many grams. You pick how many.
Units for wherever you live
Metric or imperial, per mille or percent, grams or standard drinks, your own currency.
Goals, pledges, badges
A weekly limit, a budget, a maximum session, or a pledge for a few days. 41 achievements behind them, if that sort of thing works on you.
Morning check-in
Two taps the morning after: how you feel, how you slept. It sits next to the night that caused it.
Statistics and export
Weekly and monthly trends, the hours you actually drink in, what a month costs. CSV export whenever you want.
Offline, with backups
No account, no sync. A backup is a file you keep, and it restores on a new phone.
What you drink stays on the phone
Never leaves
Your drinks, your BAC history, your notes, goals, check-ins and body profile live in a database on your device. There is no account to make and no server of mine holding a copy. Health Connect data is read on the device and never uploaded.
Leaves only when you ask
The AI coach sends what it needs to answer your question, when you ask one, through a relay to the model. The free version shows ads through Google AdMob, which collects the usual advertising identifiers and nothing from your log. Plus switches the ads off.
Most of it is free
The diary, the estimate, the calendar, the widget, the coach with its starter questions: all in the free version, with banner ads. Plus is an upgrade inside the app, monthly, yearly or paid once, and it adds the parts that cost me money or that a heavy user runs into.
- No ads
- Longer statistics ranges
- The full cocktail list
- Unlimited reminders and favorites
- A coach you can ask your own questions

Every cell is read from the app's own listing on that day, which is what German comparative advertising rules ask for and also simply the honest way to do it. If one has gone stale, tell me and I will fix it. Not the AlcoDroid you were looking for? AlcoTrack used to be called AlcDroid, without the second o; the comparison page untangles the two.
Questions people ask first
How accurate is it?
As accurate as the inputs. The formula is the standard one (Watson's body water, Widmark's blood ratio) and the elimination rate is yours to set. What it cannot see is what you ate, what medication you take, or how your liver is doing today, so treat the number as a good guess, not a reading. It is not a breathalyzer.
Can it tell me whether I can drive?
No, and it will not pretend to. If you have been drinking, don't drive, whatever the number says.
Does it work offline?
Yes. The diary, the estimate, the statistics and the widget need no connection at all. The AI coach is the one feature that does, because the model does not fit on a phone.
I don't want to count grams. Can I use standard drinks?
Yes, and you can tell the app how big a standard drink is where you live. The same goes for ounces instead of millilitres, percent instead of per mille, and your own currency for what it costs.
I used AlcDroid. Is this the same app?
Same app, same developer, new name. Your old data imports on first start, and the old backups still restore. If you meant AlcoDroid with an o, that is a different app by a different developer; here is how the two compare.
I want to stop drinking, not cut back. Is this for me?
It is built around logging what you drink, so if you have quit altogether it will mostly sit there counting alcohol-free days, which some people like. If you are still deciding, the diary is a decent way to see what you are deciding about.
Get the app
Free on Google Play for Android 9 and newer. Plus is an optional upgrade inside the app.
Formerly AlcDroid. Same developer, and your old data imports.
Reading this on a computer? Point your phone's camera at the code.
AlcoTrack estimates your blood alcohol content from what you type in. Everyone's metabolism is different, and food and medication shift it further, so treat the number as a rough guide, not a measurement. It isn't a breathalyzer and can't tell you whether you are fit to drive. Never drink and drive.
