## What is Electronics Circuit Simulator?

This app is a complete electronics workbench on your iPhone and iPad. Build circuits on an interactive schematic editor, simulate them with real Modified Nodal Analysis, and learn electronics through hands-on exploration.
VERSION 2.0 — WHAT'S NEW:
CIRCUIT CHALLENGES
Test your electronics knowledge with 9 interactive puzzles across 4 categories — Basics, Analysis, Design, and Troubleshooting. Each challenge provides a starting circuit you must modify to meet specific goals, with built-in validation that checks your simulation results.
ELECTRONICS CALCULATOR
Seven quick-access calculators: Ohm's Law, Voltage Divider, RC Time Constant, LED Resistor Sizing, Power Dissipation, Parallel Resistance, and Series Capacitance. All with real-time results in engineering notation as you type.
OSCILLOSCOPE VIEW
Dual-channel waveform visualizer with sine, square, triangle, and sawtooth signals. Adjustable frequency, amplitude, DC offset, and timebase — complete with graticule, tick marks, and measurement readouts for Vpp, Vrms, frequency, and period.
CORE FEATURES:

Schematic editor with tap-to-place components and L-shaped auto-routing wires
DC circuit simulation using Modified Nodal Analysis with Newton-Raphson iteration
50+ electronic components across 10 categories
20+ pre-built common circuits ready to load and simulate
Virtual multimeter with voltage and current probes
Undo support, save/load circuits, rotate and edit component values
Comprehensive Electronics Guide covering fundamentals, components, formulas, and safety
Interactive tutorial for new users

Built entirely in SwiftUI. No internet connection required. No ads. No subscriptions.
