Dot vs Galaxy Particles

Dot-Physics is an interactive particle sandbox where tiny glowing dots follow simple rules and grow into surprising patterns. Choose a preset world, create your own rules, or draw particles directly onto the screen. Change how colours attract, repel, chase, cluster, and spread, then watch the world come alive. Features: • Real-time particle worlds with colourful motion • Creative Mode for custom attraction and repulsion rules • Draw Mode for painting new particles into the simulation • Touch interaction for attracting, repelling, stirring, and dropping dots • Adjustable dot count, speed, damping, radius, and point size • Relaxing ambient background music • Presets for quick experiments and beautiful patterns Dot-Physics is part visual toy, part creative sandbox, and part simple science experiment. There are no scores, timers, or pressure. Just start a world, interact with it, and see what emerges.

Your face is the gravity. Galaxy Particles fills the whole screen with thin dashes of light that fly edge to edge. Your head, eyes and mouth become the masses that bend their paths. Turn your head and the field turns with you. Lean in and the orbits tighten. Open your mouth and the pull lets go, or a black hole grows where your mouth is, depending on the scene. Thirty scenes, each with its own physics: • Orbit, Rings, Halo and Galaxy: bodies circling your head • Stream, Compass, Sway, Shear and Vortex Street: currents that part around your face • Black Hole, Lens and Twin Holes: dark cores that swallow nothing but bend everything • Billiards, Marbles and Snowglobe: bodies that bounce off the edges of the screen • Elastic, Honey, Tide, Pulse and Lantern: fields that breathe, stretch and spring back …and more. Swipe left or right to move between them. Made to be calm: • Nothing on screen but the light. No buttons, no scores, no timers, no streaks. • Your face controls everything. You never touch the particles. • Slow responses. Blinking, twitching and tracking hiccups never disturb the picture. • The longer you play over time, the denser the field quietly becomes. Private by design: • Uses the front camera for Apple's on-device face tracking, which gives the app only the position and shape of your face. • The camera image is never shown, saved or sent anywhere. There is nothing to leak. • No account, no analytics, no network access. The app has no way to reach the internet. No ads, ever: • No interruptions, no pop-ups, no videos to watch. Safe to hand to a child. Requires iPhone X or later, including iPhone SE (2020 and newer). Runs entirely on your device.
