Triple Pendulum vs Von Neumann entropy
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Triple Pendulum
Read full descriptionHide full description
The motion of a triple 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.
Von Neumann entropy

This app represents von Neumann entropy for density matrix. The density matrix represents the mixed states of two states.

Verdict
The clearest difference is iOS requirement: Triple Pendulum at 7.0 against Von Neumann entropy's 18.0. On price, ads, in-app purchases and device support there is nothing between them.
