CircuitWorkbench

CircuitWorkbench brings real SPICE simulation to your Android device — draw a schematic, run the analysis, see the results. No desktop required. Built on NGSpice, the same simulation engine trusted by professional and academic circuit designers, CircuitWorkbench isn't a toy schematic viewer — it's a genuine SPICE simulator in your pocket. SCHEMATIC CAPTURE - Fast, precise component placement and wiring with intelligent snapping - Manhattan-style auto-routing keeps wires clean as you build - Built-in meter tools — Ammeter, Voltmeter, Wattmeter — drop them right onto your circuit to probe any node or branch - Mutual inductance, initial conditions, and user-defined net names for circuits that need precision REAL ANALYSES, REAL RESULTS - Operating Point (DC bias) and Transient analysis — free, unlimited - AC and DC Sweep analysis — Pro - Distortion analysis — Pro - Full waveform charting with custom vector expressions DEVICE MODEL LIBRARY - BJT, MOSFET, JFET, and Diode models with full parameter editing - Import your own SPICE .model cards directly — paste a manufacturer datasheet model and simulate with it immediately - Lossy transmission line (LTRA) and uniform RC line (URC) support for signal integrity work - Personal model library that follows you across circuits FILE MANAGEMENT THAT RESPECTS YOUR WORK - Save, Save As, and share schematics as native .sch files - Choose internal storage or your own external folder — Pro - Simulation history — parameters and result vectors are remembered per circuit, so re-running a sweep is one tap FREE TO START, PRO WHEN YOU'RE READY CircuitWorkbench is free to download and use, with Operating Point and Transient analysis available with no limits. Unlock CircuitWorkbench Pro with a single one-time purchase — no subscription — for AC/DC/Distortion analysis, external storage, and PDF export. WHO IT'S FOR Students learning circuit theory who want to check their homework without booting a laptop. Hobbyists prototyping on the go. Working engineers who want to sanity-check a topology between meetings. CircuitWorkbench is built for anyone who thinks in circuits and doesn't want to wait for a desk to verify an idea. CircuitWorkbench is under active, ongoing development — new analyses, device models, and workflow improvements ship regularly.
