Particle Life: Science Lab

What can simple rules create? Particle Life is a free science laboratory for iPhone and iPad. Change how colorful particles attract and repel one another, then watch clusters and moving patterns emerge. LEARN BY EXPERIMENTING Six guided experiments invite you to predict, change one variable, observe and explain. Explore attraction, unequal interactions, distance, friction, boundaries and emergence. Keep predictions and observations alongside your saved worlds. MAKE THE RULES Edit how each species responds to every other species. Adjust attraction, repulsion, interaction distances, particle count, friction and world boundaries. Use exact values, original presets or randomized rules to follow your curiosity. EXPLORE IN 2D AND 3D Add, erase, attract and repel particles with touch tools. Pan, zoom and orbit. Pause, advance one step, inspect a particle or replay a compatible starting arrangement while keeping your edited rules. SAVE YOUR DISCOVERIES Save complete worlds with notes, export and import .particlelife files, and share a still picture through the iOS share sheet. A COMPLETE FREE LABORATORY Every tool and experiment is free. Optional one-time tips support development without unlocking content. No accounts, ads or subscriptions. Simulations and notes stay on your device unless you choose to share them. These are simplified artificial-life rules, not a validated biological model. The particles are not living organisms. Larger populations and demanding settings can slow the simulation. Designed for iPhone and iPad, with portrait and landscape layouts.
