In mathematics, in the area of dynamical systems, a double pendulum is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior. The motion of a double pendulum is governed by a set of coupled ordinary differential equations. For certain energies its motion is chaotic. This application solves these differential equations using the Runge-Kutta method for the time stepping. You can influence the movement of the pendulum by holding your device in different positions.

Verdict
The clearest difference is price: Double Pendulum Simulation at Free against Pendulum Lab's $0.99. Double Pendulum Simulation also leads on in-app purchases (none vs 1) and iOS requirement (7.0 vs 15.0). Pendulum Lab's advantage is update cadence (every 5 weeks vs every 73 months). On ads and device support there is nothing between them.
