PocketFlow
Science, Art, and Technology in Your Pocket
PocketFlow is a unique blend of science, nature, and technology — the world's first iOS-based CFD solver supercharged by your device's GPU. Whether you're an engineer exploring vortex dynamics, a student learning about pressure flow, or simply curious about how fluids move, PocketFlow makes complex physics intuitive, visual, and interactive.
Tap to create obstacles, drag to shape flow, and watch as real-time simulations respond instantly. PocketFlow reveals the invisible patterns of motion that shape our world — from rivers to rockets — with no code, no equations, and no external computing.
Behind the scenes, it runs a high-fidelity 2D incompressible solver with volume-of-fluid tracking, turbulence modeling, and automatic stability control — all accelerated with Apple Metal, completely offline.
It's a tool for learning, a canvas for experimentation, and a playground for discovery.
Coming Soon
PocketFlow is currently in development and will be available for download soon. Whether you're a hobbyist or a professional, PocketFlow invites you to see fluid motion not just as math — but as nature.
