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.
