Description

Electronic Toolbox 2 – The classic, re‑imagined

Since 2009, Electronic Toolbox has been one of the most comprehensive electronics references and toolboxes on the App Store—for professionals, students, makers, HAMs, and hobby engineers.

With Electronic Toolbox 2, a fully modernized new edition arrives: familiar in structure, up to date technologically, and consistently evolved.

# The best and most complete electronics app—now for iPhone, iPad & Mac

Over 70 tools, tables, and references—from “A” like ASCII table to “Z” like Zener diode calculation:

Everything you need in the lab, workshop, or lecture hall, in one place.

Universal app: One purchase—three platforms (iPhone, iPad, Mac)

iCloud sync: All settings and favorites automatically on all devices

Multi‑window support: Use multiple tools in parallel—ideal for comparisons

PDF export: Save, document, or share results

Pinned tools: Keep important tools always at hand

Interactive tools: New visualizations, e.g., in the Battery Charge tool

Modern UI with Dark Mode: Redesigned, clearly structured, and easy to read

# Proven foundation, familiar workflow

Electronic Toolbox 2 stays true to its heritage—all known tools are included and have been carefully revised.

From calculators to reference data: nothing is missing, much is better.

Examples:

Resistor color code and coil calculator

NE555 and heatsink calculation

Conversion and unit tools (HEX, AWG, frequency, and more)

Parametric component search with datasheets

Tables for batteries, drill sizes, IC pinouts, packages, and more

References for boards like Raspberry Pi, Arduino, BeagleBone, Nano Pi …

Global search across all tools

Fully usable offline

No ads, no in‑app purchases

# Continuously improved—since 2009

Electronic Toolbox has been maintained and improved with passion for over a decade.

With version 2, we carry this legacy forward—on a new technical foundation for the years ahead.

Feedback from the community remains central: every suggestion helps make the toolbox even better.

# Gentle transition

The original Electronic‑Toolbox Pro remains fully usable—existing workflows are not interrupted.

Existing customers can switch to the new version via a discounted bundle.

Features like the Circuit Editor or Projects will initially remain exclusive to Electronic‑Toolbox Pro and are not yet included in this new edition.

# From the developer

Jan Roskosch built Electronic Toolbox 2 together with his father Marcus Roskosch, the developer of the original app.

A modern realization of a classic—with the same passion for electronics, precision, and quality.

# At a glance
