About Algodoo

Algodoo lets you build physical systems with simple drawing tools, then click, drag, tilt and shake them to see what happens. It covers forces, friction, fluids, optics with lasers, and motion, and it can show graphs and force vectors to make the physics visible.

It grew out of the earlier program Phun and is now free, with an optional donation. Creations can be shared on Algobox, the project's community site. There is a desktop version with an Apple Silicon update and a separate iPad version.

Strengths

  • Draw-and-play approach needs no physics or programming background
  • Simulates fluids, friction, forces and optics
  • Graphs and force visualisation help explain what is happening
  • Algobox site for sharing and downloading scenes

Limitations

  • 2D only; complex 3D mechanics need other software
  • Release dates and update frequency are not published on the homepage

Alternatives to Algodoo

Compare all

Software that can replace Algodoo for an important use case, and what changes if you switch.

  • Step

    A KDE interactive physics simulator for building two-dimensional experiments and watching them evolve.

    Step is an open-source KDE physics simulator that also works in two dimensions and lets you edit properties while running, but it runs only on Linux.

  • PhET Interactive Simulations

    Free interactive physics, chemistry and math simulations usable directly in the browser.

    FreeProprietaryWeb

    PhET Interactive Simulations runs ready-made physics, chemistry and math simulations in the browser with no signup, rather than letting you draw your own freeform scenes.
