A drink tracker with a pharmacokinetic model
Log a drink and CheersCount draws your estimated blood alcohol curve, shaped by what you ate and drank, with an honest ±25% margin.
Estimated peak 14% lower with dinner

How the estimate worksHow it works
Tap it as you have it, or add it later. Sessions start and end on their own, so there's nothing to manage.
A meal slows absorption and lowers the estimated peak. Pick light, medium or heavy, or enter your own calories.
See the estimated value now, the peak, and when you'll be back at zero, with a band instead of false precision.
Features
A clear record of the evening, with the details that change the estimate.
Food-aware estimate
Log a meal and see how it changes the estimated rise and peak. The model accounts for food instead of treating every drink as if it hit your blood at once.
Personal calibration
Own a breathalyzer? Two readings on the way down can fit your personal elimination rate. Until then, the estimate uses a population average.
Made for a shared table
Start a hangout, log a round for the table, and include friends who haven't installed the app.
The method, in plain language
CheersCount models absorption, distribution and elimination over time. Food and drink strength shape the curve, and your own readings can calibrate its elimination rate.
An estimate, not a test
It's an educational estimate, not a measurement or a fitness-to-drive test. When in doubt, don't drive.

Built in Austria
I'm Andreas, and I build CheersCount on my own in Austria.
I wanted a drink tracker that treats an evening as something to understand rather than something to be scolded for, and that shows its uncertainty instead of hiding it. There's no coaching, no score and no streak to lose.
If something's wrong or missing, write to me at support@cheerscount.com. It comes straight to me.

FAQ
It models alcohol absorption, distribution and elimination over time, using drink details, food and your profile. A personal elimination rate can be fitted from breathalyzer readings.
It's an estimate, not a measurement. Individual results can vary roughly ±20-30% from a population model, so the app shows an uncertainty band rather than presenting the value as exact.
No. CheersCount can't tell you whether you're fit or legally allowed to drive. Don't use an estimate for that decision.
No. You can try CheersCount without creating an account. Your local profile and its data can later be carried into an account.
Yes, in Safari: open the web app and add it to your home screen. There's no App Store app yet. On Android you can use the Play Store app or the web app.
Drink logging, history, goals, the estimate and time until zero, calibration and hangouts are free, and the curve of a finished night stays free too. Pro adds the live curve while the night is on, unlimited templates, custom icons, expense tracking, chat and posting stories.

A one-litre Maß of ~6% festival beer holds about 47 grams of ethanol - close to four shots. Yet beer sits near the slow end of an absorption curve that peaks at around 22% ABV, not at the strongest drink.
