About

Flocking Simulator

Explore emergent behavior and steering rules with a "boids" simulation. Adjust forces like separation, alignment, and cohesion to create lifelike motion. Experiment with visual options and observe instant reactions to your changes.

Highlights
  • Adjustable flocking forces (separation, alignment, cohesion)
  • Customizable perception radius, speed, and steering
  • Visual options: boid shape, color modes, debug overlays
  • Real-time swarm reaction to parameter changes
  • Learning emergent behavior and steering rules
  • Generative visuals and relaxing motion

Flocking Simulator is a real-time “boids” playground where simple rules create surprisingly lifelike motion. Build your perfect swarm by adjusting the core forces: • Separation, Alignment, Cohesion • Perception radius, max speed, max steer • Drag (friction), noise (jitter), bias • Optional wall bouncing Visual options: • Triangle or circle boids • Color modes: Solid, Velocity, Rainbow • Debug overlays: vision radius, direction vectors, stats/FPS Great for: • Learning emergent behavior and steering rules • Generative visuals and relaxing motion • Quick experiments—change a slider and watch the swarm react instantly Note: Fast motion and bright colors may affect users sensitive to motion.

Physics Playground is a hands-on science app with 102 interactive labs — from pendulums and black holes to rainbows, magnets and melting ice. Every lab is a live simulation you control with your finger, or with your hand in the air, so you can see how the world works instead of just reading about it. THREE WAYS TO EXPLORE • Explore — pick any lab and start playing. • Learning Journey — follow a short story one step at a time: Things that move, Light and sound, Earth and space. • Curiosity Lab — ask your own science question by typing or speaking and get a short, friendly answer. Tap "Draw it!" for a picture, save pictures to Photos, or have the answer read aloud. 102 LABS How the World Works (44 labs): Colour Mixer, Rainbow Spinner, Heavy or Light?, Drop Zone, Slide Race, Bouncy Balls and many more everyday science experiments Mechanics: Simple Pendulum, Projectile Motion, Elastic Collision, Spring Oscillator, Inclined Plane, Pulley System, Circular Motion and more Waves and Sound: Wave Interference, Doppler Effect, Standing Waves, Resonance Studio Light and Optics: Light Refraction, Light Reflection, Light Polarization, Rainbow Maker Electricity and Magnetism: Electric Field, Capacitor Charging, Circuit City, Magnet Maze, Electromagnetic Induction, Tesla Coil Heat and Matter: Gas Particles, Entropy & Disorder, Tiny Heat Engine, Crystal Builder, Phase Changer Quantum and Nuclear: Double Slit, Photoelectric Effect, Quantum Tunnel, Radioactive Decay, Nuclear Fission, Nuclear Fusion, Half-Life Detective Space and Relativity: Orbital Mechanics, Black Hole, Exoplanet Hunter, Relativity Rocket, Gravity Lens Earth and Energy: Tectonic Plates, Weather Balloon, Solar Grid, Wind Tunnel Fluids: Fluid Flow, Buoyancy, Vortex Lab HOW IT WORKS Touch the canvas to grab and interact with the simulation — there is no right or wrong way to explore. Adjust variables like gravity, mass, length and velocity with the built-in sliders and watch the results change instantly. For a hands-free experience, turn on the camera and control labs with your hand in the air. Hand tracking runs on your device — no images or video are stored or sent anywhere. CHALLENGES Every lab has a challenge that teaches the key idea behind it. Complete it to earn a star and track your progress across all 102 labs on the progress screen. REAL PHYSICS LAWS The simulations are built on real physics equations, and the app shows the governing laws so you can connect what you see to real formulas. ABOUT CURIOSITY LAB Answers and pictures are created by AI (Google's Gemini models) for learning and fun, and can sometimes be wrong. Every answer has a Report button, and questions are limited each day. Curiosity Lab asks for your permission before it shares a question with Google Gemini, and you can turn this off at any time in Privacy choices. WHO IS IT FOR Students, teachers and anyone curious about how the physics world works — from first questions to university physics. It makes an excellent companion to classroom learning, and no prior knowledge is needed. PRIVACY Play as a guest — no name or email needed. A grown-up can choose to sign in with Apple or Google to keep progress across devices, and can delete the account in the app at any time. You decide whether to share usage analytics. Camera processing happens entirely on your device. Privacy policy: https://physics-playground-24c5e.web.app/privacy Terms: https://physics-playground-24c5e.web.app/terms

Verdict

The call

Flocking Simulator and Physics Playgrounds are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
