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.
