OrbitLab is a visual N-body gravity simulator for exploring orbital physics. Create custom systems with stars and planets, adjust their mass, size, position, and velocity, and watch them evolve in real time. Use undo/redo, time controls, orbit trails, and live diagnostics to experiment with stability and motion. OrbitLab makes gravity easy and engaging to explore. Compare the orbits of the planets orbit at the same time. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
