The Problem with One Researcher
Sixty-three measurements across three cities is a start. It is enough to identify a pattern and enough to raise an alarm. But it is not enough to change anything. One person with a jeweler's scale cannot audit the approximately 60,000 bars in the United States. The scope of the problem demands a different approach—one that scales with the number of people who care about getting what they pay for.
Pint Patrol: A Crowdsourced Answer
Pint Patrol is a mobile application designed to turn every interested beer drinker into a field researcher. There are two ways to contribute:
Snap a Photo (Everyone)
The simplest way to help: take a photo of your drink and tell the app what glass it came in and where you are. No equipment needed. Every photo teaches the app what glassware each venue uses, building toward a future where Pint Patrol can estimate pour volumes from a picture alone. You are training the system just by having a beer.
Weigh Your Pour (Field Agents)
For those who want to go further, a pocket jeweler's scale turns a casual photo into a precision measurement:
- Photograph your full glass on the scale. A jeweler's scale is accurate to 0.01 oz, portable enough to fit in a pocket. The app reads the scale display automatically using character recognition.
- Drink your beer. Enjoy it. This is the easy part.
- Photograph the empty glass on the scale. The app reads the empty weight the same way.
- The app does the math. Using the mass difference and the beer's density (calculated from the ABV), Pint Patrol computes the actual volume poured and compares it to the claimed serving size.
- Your measurement joins a shared database. Every submitted pour is geotagged to the venue and vetted by a human reviewer for accuracy before it appears on the public map.
Every scale measurement directly advances the app's ability to estimate volumes visually. The more weighed pours we collect alongside photos, the closer we get to a world where no scale is needed at all.
The result is a living, growing dataset: a public record of which bars pour honest drinks and which do not. No legislation required. No government inspectors. Just consumers with phones and a shared commitment to knowing what they're paying for.

How It Works
- Score a Pour. Tap "New Pour," photograph your drink, identify the glass, and tell us where you are. That's it — you're contributing.
- Have a scale? The app walks you through weighing the full and empty glass for a precision measurement. Skip this step anytime — photos alone are valuable.
- Find a Pint. Browse the map to see venues color-coded by pour accuracy: green (99%+), yellow (90–94%), red (below 90%).
- Want to share your data? Sign in with your email to get an agent number and submit pours to the public database. No account needed to use the app privately.
Want to Go Further?
A jeweler's scale ($10–$20 online, pocket-sized, accurate to 0.01 oz) turns your photos into precision measurements. Every weighed pour directly trains the app's visual estimation engine — the more scale data we collect alongside photos, the closer we get to a world where no scale is needed at all.
Where We Need Help
Geographic coverage. The initial study covered three American cities. But short pours are not an American problem alone — Pint Patrol is built to go wherever beer, wine, and cider are poured. The more cities and countries represented, the clearer the worldwide picture becomes.
Honest venues. If you own or manage a bar and you pour honest measures, Pint Patrol is your friend, not your enemy. A high pour-accuracy score is free advertising for the bars that earn it.

This is a beta. Things will break. When they do, email steve@isitapint.com with what happened, what you expected, and a screenshot if possible.
The Vision
Imagine opening an app before you choose a bar and seeing, at a glance, which nearby venues consistently deliver what they promise. Green markers for honest pours. Red markers for short ones. A consumer tool as straightforward as checking a restaurant's health inspection grade—except built by the people who actually drink there.
This is not about punishing bars. It is about creating transparency where none currently exists. Regulatory systems around the world have repeatedly declined to enforce pour standards. Pint Patrol is the alternative: accountability from below, powered by data, and open to anyone who believes that when you pay for a pint, you should get one.
