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.
