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.
