About this app

Serious calculator tools. Gassy personality.

Flatulator brings useful everyday math tools together in one colorful calculator app, with a goofy green gas-cloud mascot and just enough ridiculousness to keep things interesting.

Whether you're checking some quick math, splitting a dinner bill, working through a scientific calculation, or converting units, Flatulator is designed to get you an answer quickly without feeling like every other calculator on your phone.

And if you want a little chaos with your calculations, turn on the optional sound effects and let the mascot do what a gas cloud does best.

What’s Inside

Basic Calculator

Fast, straightforward calculations for everyday math, including addition, subtraction, multiplication, division, percentages, and quick number checks.

Scientific Calculator

A more powerful calculator for those times when basic arithmetic just isn't enough.

Tip Calculator

Calculate your tip, split the bill between multiple people, round the total, and quickly see what everyone owes.

Unit Converter

Convert common measurements across length, mass, temperature, volume, area, speed, time, data, and more.

Useful When You Need It. Ridiculous When You Want It.

Flatulator can behave like a perfectly normal calculator.

Turn the sounds off and get things done quietly.

Or don't.

Enable the optional sound effects, tap some buttons, and let your little green gas cloud bring some unnecessary enthusiasm to mathematics.

Built a Little Differently

Flatulator started with a simple idea: a useful app doesn't have to be boring.

I've never been the kind of person who gets excited about staring at a plain calculator, so I wanted to build something that could handle the practical stuff while having a little personality of its own.

Flatulator is an independent solo-dev project, and I'm continuing to improve it with new features, refinements, and plenty of questionable ideas.

Use it for the math.

Keep it for the personality.

Serious math. Silly sounds.

What’s new

Refreshed the Unit Converter layout and unit selection for clearer, more responsive conversions. Added more varied mascot reactions synchronized with sound playback. The equals button now uses long fart sounds. Removed the experimental Notebook feature.
