About this app
Electronic circuit simulator (English, Spanish and Portuguese), made for
electronics students and teachers — from technical school to college. Build your
circuit with your finger, connect with wires and simulate instantly. Works
OFFLINE: once installed, it needs no internet.
▶ THE SIMULATION COMES ALIVE
It's not a static drawing: CURRENT flows through the wires as particles, the lamp
LIGHTS UP based on power and the motor SPINS based on current. You see what
happens, not just numbers.
▶ REAL ANALYSIS
• DC: operating point, voltages and currents node by node.
• Transient: built-in oscilloscope with cursors, measurements (Vpp, RMS,
frequency) and adaptive step for precise traces.
• Bode (AC): frequency response, gain and phase.
• DC component sweep and a live results panel, node by node.
▶ POWER ELECTRONICS (what other simulators don't include)
• Thyristor (SCR), TRIAC and DIAC with phase control — build the real wall
DIMMER and watch it chop the waveform.
• IGBT for switching and choppers.
• Optocoupler and transformer for isolation.
• Relay with real physics: inductive coil, hysteresis and flyback spike.
The industrial-electronics lab the technical curriculum needs.
▶ OVER 40 COMPONENTS
Resistors, capacitors, inductors, diodes, LED, Zener, lamp, fuse, potentiometer,
DC motor, relay, buzzer, 7-segment display, DC / sine / PULSE (PWM) / noise
sources, BJT and MOSFET transistors, operational amplifier, transformer, the
NE555 timer and logic gates (NOT, AND, OR, NAND, NOR, XOR) for digital circuits.
Edit any value with engineering notation (4.7k, 1µ).
▶ OVER 40 READY-TO-LEARN EXAMPLES
Dividers, rectifiers, Wheatstone bridge, filters and resonance (Bode),
110 V → 12 V power supply, op-amp amplifiers, 555 oscillator and monostable, a
relay switching a lamp, a DIAC dimmer, a logic-gate latch, a motor with a
rheostat and more — each with its animated schematic and explanation.
▶ MADE FOR LEARNING
• In English (also Spanish and Portuguese).
• Touch editor with real icons: place, wire, edit, simulate.
• Save your circuits, export to PNG and share them via WhatsApp or Drive right from the app.
▶ LIGHT AND FAST
Runs even on school netbooks and Chromebooks. Its own simulation engine, no
gimmicks: it solves with the same methods as a professional simulator.
Ideal for analog and power-electronics classes: rectifiers, amplifiers, filters,
phase control with thyristors, timers and digital circuits — experiment without
burning anything.
