ElectroSim: Circuit Simulator

ElectroSim is a mobile electrical wiring simulator for students, apprentices, electricians, and instructors. Build circuits by dragging components, snapping to grid, and running real-time simulations for series and parallel wiring. The app works offline with no ads, making it ideal for classrooms, labs, and self-guided practice.

Key features include drag-and-drop components, pan/zoom, undo/redo, and testing circuits for open/closed paths and load behavior. Free access covers circuit building and basic simulations; Pro options unlock unlimited local saves and extra components. It’s a learning aid, not a certification tool, and you should follow local electrical codes.
