Circuit Calculator Pro vs Electronics Circuit Simulator

Circuit Calculator Pro is a practical electronics toolkit for students, makers, and engineers. Use 13 calculators in one app: • Ohm's Law (V, I, R, P) • Resistors Series/Parallel • Voltage Divider • LED Resistor • RC Time Constant • Capacitors Series/Parallel • Inductors Series/Parallel • Reactance (Xc/Xl) • Power & Energy • Wire Voltage Drop • LED String • Loaded Divider • E-Series Finder Built-in workflow tools: • Save recent calculations • Organize results into projects and folders • Copy/share results instantly • Export to PDF and image (Premium) Reference library included: • Resistor color code guide • Capacitor code guide • Formula cheat sheets • Electronics glossary Circuit Builder (Premium): • Drag-and-drop components • Connect nodes on a grid canvas • Run circuit analysis and view node voltages/currents • Save and reopen circuit files Free plan includes core calculators with ads. Premium is a one-time purchase that unlocks advanced calculators, circuit builder access, expanded limits, and ad removal.

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.
