Scientists did not just make a joke app. They turned a basic body function into a data question with real medical stakes.
Quick Take
- The CSIRO “Chart Your Fart” project asks Australians age 14 and up to record flatulence for at least three days.[3][5]
- The app tracks more than count alone. It asks users to rate quantity, quality, stench, loudness, duration, linger, and detectability.[1][2][3][5]
- The project aims to build a chart of what “normal” wind may look like across different groups.[2][3][5][6]
- The best reading is not “farting proves gut health.” It is that flatulence may help researchers map patterns, but context still matters.[4][7]
A Laugh-Getting Name Hides a Serious Research Question
“Chart Your Fart” sounds like a punchline, but the idea behind it is more sober. Australia’s national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), says the app exists to better understand flatulence patterns and concerns as part of public-led research.[3][6] The project recruited people to log their gas over a short window, then used that information to explore what normal wind may look like in different groups.[2][3][5]
That matters because the real question is not whether people fart. They do, often. The harder question is whether a self-tracked app can help researchers describe a useful population range. The available material says yes, at least as a descriptive tool. It does not say the app can diagnose disease on its own.[4][7]
What the App Actually Measures
The app does not stop at a simple tally. Coverage of the project says users rate loudness, duration, smell longevity, detectability, stench, quantity, and quality.[1][2][3][5] That design choice tells you a lot. The researchers are not treating flatulence like a yes-or-no event. They are treating it like a symptom with layers, which is how many real health clues work in practice.[1][2][3]
CSIRO’s own materials say participants must be 14 or older, live in Australia, and record for at least three days.[5] The project page says the goal is to gather valuable insights into flatulence patterns, and the Google Play listing says the team wants enough detail to answer how often people fart and how that varies across the nation.[5][6] That is population research, not a bedside test.[5][6]
Why Doctors Would Not Call This a Simple Gut-Health Score
The cleanest warning against overreading the chart comes from the same source that makes the project interesting: the data are broad, not clinical. ABC’s discussion says gas production changes with diet and gut bacteria, and that conditions like Crohn’s disease, fundoplication, irritable bowel syndrome, and celiac disease can all be linked with increased gas.[4] That means fart frequency may point to something, but it does not point to one thing.[4]
The other caution is even simpler. The project itself describes a cross-sectional study of daily flatulence patterns reported by people in Australia.[7] Cross-sectional studies can describe what is happening at one point in time, but they do not, by themselves, prove that a given chart works as a diagnostic tool.[7] A normal-range chart can be useful. A health verdict from a fart count is a different claim entirely.[7]
So How Do You Rank?
If you are judging your own “score,” the smartest answer is not to chase a magic number. The available reporting says healthy adults may pass gas somewhere between about seven and 20 times a day, while another source says about 10 to 25 times a day.[2][6] That spread alone shows why rigid cutoffs are shaky. Diet, fiber, and other factors can move the number around, even in healthy people.[2][4][6]
If your gas changes suddenly, becomes painful, or comes with bloating, bowel changes, weight loss, or food intolerance, the chart should not be your final stop. The project can help researchers map patterns, and that is useful. But the body rarely gives one clean answer. It gives clues, and then asks for judgment.[4][7]
