PocketFlow

Fluid is nature. Nature is art.

PocketFlow is a window into the invisible beauty of flow. Built with cutting-edge GPU solvers and crafted for the palm of your hand, PocketFlow blends science, art, and intuition into a single, immersive experience.

Whether you’re a student, a hobbyist, a king, or an axolotl, PocketFlow lets you:

- Explore the physics of fluid motion without the clutter of code or equations
- Visualise complex flow behaviour with the elegance of digital brushstrokes
- Build true physical intuition by interacting, observing, and experimenting

PocketFlow is the world's first fully mobile GPU CFD solver, delivering real-time simulation of 2D free-surface and pressure flow, entirely on-device. Under the hood:
- Incompressibile solver
- Subgrid-scale turbulence
- Automatic stability control
- GPU-accelerated via Apple Metal
- Fully offline

You don’t need a PhD in numerical methods to appreciate how flow curls around a resting turtle or slips past a river stone. With PocketFlow, the world of fluid mechanics is accessible, tactile, and stunningly beautiful.
