Fixed a bug where a few presets (Figure Eight, Butterfly, Pythagorean, Dance) showed emoji faces instead of colored bodies. Fixed onboarding buttons being hard to see on some devices. General reliability and stability improvements.
Gravity simulator: watch orbits spiral into chaos. Free, offline, no ads.
See the real three-body problem in motion. Three bodies, one gravitational field, and no way to predict what happens next - this is the actual physics behind the famous unsolvable problem (and the novel/show that made it famous). Drop in two, three, five bodies and watch orbits that look stable... until they don't. This is a real gravity simulator, not just a visual. Choose Newtonian, simplified relativistic, or simple orbital physics. Pick your numerical integrator (fast Euler or precise Runge-Kutta 4). Tune gravity strength, softening, collisions, and more. FEATURES - Real orbital mechanics: Newtonian gravity, relativistic corrections, multiple integrators - Watch chaos emerge from simple rules - tiny changes in starting position lead to wildly different outcomes - Smooth, glowing, hypnotic to watch - Fully offline, no account, no ads, no tracking - Free Whether you're curious about the real science after the book or show, studying chaos theory, or just want something oddly satisfying to stare at - this is orbital chaos you can actually play with.
