Code the Beat is a unique and immersive experience where learning to code becomes an adventure through music. Guided by the animated character BeatBot, players dive into the world of programming while creating their own musical compositions using real Swift code. Learn Swift, One Beat at a Time Each level introduces a fundamental coding concept in an interactive and creative way. Whether you’re new to coding or want to experience it in a fresh format, Code the Beat makes learning engaging and intuitive. • Variables: Start your journey by playing notes on a virtual piano. As you play, you’ll see how variables can store musical values—bridging sound and code in real time. • Functions: Use a DJ pad to trigger chords and learn how functions group together instructions to create reusable code blocks—just like combining notes to form a chord. • Arrays: Drag and drop chords to create your own musical sequence, understanding how arrays store and manage collections of values. • Loops: Turn your chord sequence into a loop to discover how iteration works. Watch your music repeat endlessly while learning the basics of for and while loops. • Conditionals: Add drum sounds at specific beats and learn how conditions like if, &&, and || control logic in programming, affecting how and when code executes. A Retro, Accessible Visual Experience The game is styled in nostalgic pixel art, designed entirely using Aseprite. Each visual element, from the animated BeatBot to floating musical notes, is carefully crafted to make learning fun. Users can also enable OpenDyslexic font in the main menu, ensuring an inclusive experience for those with dyslexia or who prefer an alternative to the pixel font. Interactive Sound & Animation Code the Beat features responsive audio and animations throughout the app. Touch piano keys, trigger chords, and watch your code come alive through visual feedback and electric piano sounds—all recorded by the developer. For Learners of All Ages Whether you’re a curious student, a creative coder, or someone looking to combine music and logic in a new way, Code the Beat is designed for you. It’s not just a game—it’s a playful introduction to the world of software development through a universal language: music.
Physics Playgrounds

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 clearest difference is iOS requirement: Physics Playgrounds at 15.0 against Code the Beat's 17.5. On price, ads, in-app purchases and device support there is nothing between them.
