Wirebench: Electronics Tools

A full electronics bench in your pocket — 24 calculators, reference tables, pinouts and safety guides. Works completely offline. No ads, no account, no tracking.

Wirebench is a bench instrument for your pocket — a fast, offline toolkit for electronics and electrical work. Built for technicians, electricians and students who need the right number now, not a web search.

EVERYTHING WORKS OFFLINE No account. No ads. No tracking. Every calculator, table and guide works with the phone in airplane mode, on a roof or in a basement.

24 CALCULATORS • Ohm's law, power, voltage divider • Resistor color code — decode bands, or get bands from a value • LED series resistor and multi-LED array planner • Series/parallel networks, and parallel trim to hit a target value • RC/RL filter cutoff, reactance, 555 timer • Op-amp gain, decibels and dBm, RMS ↔ peak, ADC resolution • Cable voltage drop, three-phase power, transformer ratios • PCB trace width (IPC-2221), heat sink sizing, LM317 regulator • Y-Δ transform, wavelength, battery life

BUILT FOR REAL BENCH WORK • Type values the way you say them — 4.7k, 100n, 2n2 all just work • Switch between metric and imperial: mm² and metres, or AWG and feet • Every calculation is saved, so you can pick up where you left off • Pin anything you use often to the dashboard • Search across calculators, tables, pinouts, components and safety at once

REFERENCE THAT LOADS INSTANTLY 14 tables covering preferred values, capacitor codes, SMD packages, IP ratings, logic levels, regulators, batteries and more. Connector pinouts, component specs, and a tip a day.

SAFETY Lock-out/tag-out, PPE, arc flash and electric shock first aid — written to be read fast when it matters.

ENGLISH AND ARABIC Fully translated, with proper right-to-left layout. Numbers stay readable in both, the way a real meter shows them.

WIREBENCH PRO — ONE-TIME PURCHASE Pay once, yours forever. No subscription, and it keeps working offline. • Export any calculation as a professional PDF report, with your company or technician name on it — print it or send it to a client • See the waveform: the 555's real output traced on a scope grid, and filter response drawn as a Bode plot

Your first exports are free, so you can see exactly what you'd be buying before you decide.

For information only — not a substitute for certified training, local codes, or emergency services. Always verify against the standards that apply where you work.
