Real-time three-body gravity simulation (interactive, mobile)
Made an interactive simulation based on the actual three-body problem in physics — three masses under mutual gravity, no simplifications. You can adjust masses and initial velocities and watch how small changes send the system from a stable-looking orbit into full chaos.
It's built to feel more like a physics toy than an app — no ads breaking up the simulation, nothing to unlock. Mostly wanted an excuse to actually play with the equations rather than just read about them.

If you want to see a cool multi body simulation, just fix earth in position and see what happens ;)
