Simple Machines by Tinybop is an award-winning educational app designed for children aged 4 and above. It is the fourth app in Tinybop’s Explorer’s Library series. This sandbox app allows kids to experiment with six simple machines: levers, pulleys, inclined planes, wedges, wheel and axles, and screws. The app helps kids to learn about force and motion, actions and reactions, inputs and outputs, conservation of energy, mechanical advantages, and tradeoffs.

The app comes with a free handbook that contains facts, interaction hints, and discussion questions to support learning in the classroom or at home. The app also integrates with STEM curriculum, allowing kids to alter and test each machine to learn more about the physics behind it. The app features original artwork by James Gilleard, and allows kids to destroy a castle, make music, send satellites into orbit, and more. Sophisticated sound design rewards experimentation, and smart features use your device’s camera to bring your kids’ world into the app.
