Physics Playground is an interactive science app featuring 38 real physics experiments across mechanics, waves, optics, electricity, magnetism, thermodynamics, quantum physics, fluids, electromagnetism, nuclear physics, and astrophysics. Every experiment runs as a live simulation on your screen. You control it directly with your finger β drag the pendulum, aim the projectile, position charges in the electric field, adjust wave frequencies, and watch the physics respond in real time. HOW IT WORKS Touch the canvas to grab and interact with the simulation. Every experiment responds to your input β there is no right or wrong way to explore. Adjust variables like gravity, mass, length, and velocity using the built-in sliders and watch the results change instantly. For a truly hands-free experience, enable the camera and control experiments with your hand in the air. The app uses on-device AI to track your hand movements in real time β no data is sent to any server. EXPERIMENTS INCLUDED Mechanics: Simple Pendulum, Projectile Motion, Elastic Collision, Spring Oscillator, Gravitational Field, Inclined Plane, Circular Motion, Torque and Levers Waves and Sound: Wave Interference, Standing Waves, Doppler Effect, Sound Waves Optics: Snell's Law and Refraction, Lens and Focal Point, Double Slit Experiment, Diffraction Grating Electricity and Magnetism: Electric Field Visualizer, Magnetic Field Lines, Electromagnetic Induction, RC Circuit Thermodynamics: Ideal Gas Law, Heat Transfer, Carnot Cycle, Entropy and Disorder Quantum Physics: Quantum Tunneling, Wave Particle Duality, Photoelectric Effect, Heisenberg Uncertainty Fluids: Bernoulli Principle, Archimedes and Buoyancy, Fluid Dynamics, Surface Tension Nuclear Physics: Nuclear Fission, Nuclear Fusion Astrophysics: Orbital Mechanics, Black Hole Gravity, Stellar Evolution, Escape Velocity CHALLENGES Every experiment has a built-in challenge that teaches the key physics concept behind the simulation. Complete the challenge to earn a star. Track your progress across all 38 experiments from the progress screen and see how many you have mastered. REAL PHYSICS LAWS Each simulation is built on actual physics equations. The app displays the governing laws for every experiment so you can connect what you see on screen to real formulas. Variables like gravity, mass, angle, frequency, and charge are all adjustable, letting you run the same experiment under different conditions. WHO IS IT FOR Physics Playground is designed for students, teachers, and anyone curious about how the physical world works. It is suitable for middle school through university level and makes an excellent companion to classroom learning. No prior physics knowledge is required to enjoy the simulations. The app is rated 4 and above with no objectionable content. PRIVACY Physics Playground signs you in anonymously. No name, email address, or personal information is ever collected or required. Your experiment progress is saved to the cloud using your anonymous account. Camera processing happens entirely on your device, and no images or videos are stored or transmitted.

Verdict
The clearest difference is in-app purchases: Physics Playgrounds at none against Flashy's 1. Flashy's advantage is update cadence (every 4 days vs every 4 months) and iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.
