Physics Playground App vs Minute Concepts

Physics Playground turns science into games you play with your hands. Fire a cannon, slide pucks across the ice, fold a protein, crack a cipher, bend starlight around a black hole and forge a star. Every game runs on real physics, chemistry, biology, math or computer science, so you learn by doing, not by reading. 63 GAMES, FIVE SUBJECTS From projectiles, orbits and lasers to entanglement and the Big Bang; atoms, reactions and batteries; cells, genes and the immune system; fractions, fractals and calculus; logic gates, sorting, networks and machine learning. Each game has its own controls and its own goal. PLAY AT YOUR LEVEL Pick Curious Kid, Teen, Undergrad or PhD. Games start on Easy, Normal or Hard to match, and PhD turns off the hints for numbers only play. Free Play lets you experiment with no clock. EARN EVERY STAR Clear stages, earn up to three stars, beat your best score and collect badges. Light up your constellation and unlock the Universe Tuner when you master them all. BUILT FOR IPHONE DUO Fold it into a tabletop and the hinge aims the cannon. Open it like a book and the game spreads across both halves, with controls on their own side. Close it and keep playing on the outer screen. NEW GRAPHICS, SMOOTH AT 120 HZ Glowing particles, warped spacetime, lensed starlight and live fractals, with haptics tuned to every bounce and blast. GO DEEPER Every game links trusted sources: textbooks, papers, lectures and courses. Works on iPhone, iPad, Mac and Apple Vision Pro. Ask Siri to open a game. No account, no ads, no tracking.
