Comparison

BAC and drink-tracker apps compared.

Ten apps that estimate or measure blood alcohol, or log what you drink, put to the same eight questions. I build one of them, CheersCount, so read it with that in mind. Every other app is described from its own store listing or website, and where a listing doesn't mention something, the table says so rather than guessing.

Written by Andreas, who builds CheersCount. Listings checked on 30 October 2026.

The short answer

If you want an estimated curve that accounts for what you ate, CheersCount, Abvy and AlcoBalance are the three apps here whose listings or websites say food is part of the estimate. If you want a measurement rather than an estimate, you need a breathalyzer, and BACtrack's app goes with its devices. For a long-running Android diary with a home-screen widget, AlcoDroid and AlcoTrack are the established picks. For beer ratings and a social feed, it's Untappd.

At a glance

The same columns for every app. "Not stated" means the app's listing or website doesn't say; the app may still do it.

What each app is built for

CheersCount

A drink log that turns a night into an estimated blood alcohol curve, built for people who drink and want to know what an evening did. The model weighs food, drink strength and your body, and two breathalyzer readings on the way down can calibrate it to your own elimination rate. It isn't a sobriety or coaching app.

Abvy

The closest rival to CheersCount: a live curve for one evening with pacing ("when the next one is fine"), optional breathalyzer calibration, widgets and a published method. Everything stays on the phone, with no account and no server, and there is no free tier. Listing

AlcoDroid

A long-running Android drink diary with a blood alcohol estimate, trends by week, month and year, spending, and export to text files. Over a million installs on Google Play, and no subscription. Listing · AlcoDroid and CheersCount, point by point

AlcoTrack

An Android tracker that combines a live blood alcohol chart with a drink diary, a cocktail list, statistics and sleep and heart rate from Health Connect. It also leans towards mindful drinking. Listing

AlcoBalance

An evening-curve tracker with a "one more?" forecast and weekly analytics, and one of the three apps in this list that state food is part of the estimate. Its listing says quitting isn't the goal. Listing

Alcocurve

A party-night curve app with drink templates and live sessions where friends see each other's estimates. The closest to a shared evening in this list besides CheersCount. Listing

AlcoInsights

A web app for moderate drinkers with live estimates, session history, goals and AI insights in Pro. Like CheersCount, it runs in the browser rather than from a store. Listing

AlcoPilot

A small German calculator: log drinks, get a number and the time until it reaches zero, with nothing stored off the phone. Listing

BACtrack

The companion app for BACtrack breathalyzers. It records what the device measures, which is a different thing from every estimate on this page. Listing

Untappd

A social network for beer, wine and spirits: check in what you drink, rate it, see what friends and venues are pouring. No blood alcohol at all, and it isn't trying to be a tracker. Listing

When another app is the better pick

A fair comparison has to cut both ways. Here's where I'd send you elsewhere.

You want a measurement, not an estimate

Only a breathalyzer measures. BACtrack's app goes with its devices. CheersCount can take your own breathalyzer readings to calibrate the curve, but it doesn't connect to a device.

You want a native iPhone app or Apple Watch

CheersCount runs on iPhone as a web app in Safari, not from the App Store. AlcoBalance has an iPhone and Apple Watch app (on iPhone it shows grams rather than blood alcohol), and Alcocurve has an iPhone app.

You want everything to stay on your phone

Abvy, AlcoTrack and AlcoPilot keep the data on the device with no account. CheersCount stores your log on its servers in the EU so it can sync and share evenings.

You want a widget and no subscription

AlcoDroid has a home-screen widget, and a one-time purchase removes its ads; Abvy and AlcoTrack have widgets too. CheersCount has no widget, and its paid tier is a subscription or a one-time lifetime purchase.

You want ratings and a beer feed

That's Untappd. CheersCount logs drinks for the curve and doesn't rate them.

Where CheersCount falls short

  • The live chart of a night that's still running is Pro. On Free you still get the estimated numbers and the estimated time until zero, and finished nights show their full curve.
  • Friends, hangouts and chat need an account, and community chat also needs Pro. Without an account you get the full personal tracker.
  • Crash reports (with a random ID, never your name) and anonymous usage statistics are on by default and can be switched off in Settings. There are no ads and no data is sold.
  • It's not open source, and the model's slowdown below about 0.15 ‰ is a population average, not yours, so the estimated time until zero is approximate.

What I left out, and why

The table covers apps for people who drink and want to see what a night did. On purpose, it leaves out:

  • Apps for quitting or cutting down, such as MyDrinkaware and DrinkControl. They're built for a different goal, and a blood alcohol curve isn't what they're for.
  • Apps that rank friends by how much they drank.
  • Apps whose store listing presents the estimate as a check of whether you can drive.
  • IntelliDrink, which is no longer in the App Store.

See your own curve

The free calculator runs the same model as the app, with no sign-up. The app keeps every night and starts with a 30-day Pro trial; nothing is charged when it ends.
