About this app

Your electrical workbench, wherever the job takes you.

Sparky Bench brings electrical calculators, conversions and practical references together in one organised app. Run calculations on your device, keep your favourite tools close, and work without an internet connection.

CABLES AND PROTECTION
Explore conductor sizing, protective-device coordination, voltage drop, current-carrying capacity, short-circuit calculations and cable losses. Select IEC, NEC or CEC profiles where supported by the tool, and review its assumptions and installation conditions.

POWER, CIRCUITS AND MOTORS
Calculate current, voltage, active, apparent and reactive power, power factor, resistance and impedance. Work with motor power, torque and other motor calculations.

WIRE CONVERSION
Convert between AWG, SWG, cross-sectional area and diameter in one place. Swap the conversion direction without re-entering the result. Gauge matches are marked as approximate where appropriate.

REFERENCES AT HAND
Find torque references, component codes, circuit formulas, pinouts and measurement tools through compact tabs and search.

MADE FOR EVERYDAY USE
• Values and their units stay together.
• System, Light and Dark themes.
• Editable Quick Access and saved tool order.
• Favourites, preferences and tool order saved locally.
• Report export and preference backups.
• 100 languages available offline, including English and Romanian. Additional packs use automatic translation; some technical text remains in English.

TRY IT, THEN KEEP IT
Try the tools for 7 days, then unlock permanent access with one purchase. No subscription and no automatic charge at the end of the trial. Your settings, favourites and saved calculation data remain on your device when the trial expires. Restore a purchase using the same store account. Purchases apply to the platform/store where they were made.

Calculators support your work: check the selected method, local requirements, installation conditions and equipment information before applying a result. Internet access is needed for store purchases and restoration; the calculation tools work offline.

What’s new

Sparky Bench 2.0 introduces a redesigned Workbench, editable Quick Access, saved tool order and System, Light and Dark themes. Includes unified wire conversion, expanded torque references and clearer calculation reports. Improved Android status-bar spacing and language selector. Calculators and 100 language packs work offline. Existing purchases, trial progress, favourites and settings are preserved. Seven-day trial and one-time unlock remain unchanged.
