About Sparky: Electrical Calculators
Sparky is the electrician field kit built for fast jobsite math, cleaner panel work, and inspection-ready documentation. Run the electrical calculations you reach for every day without digging through notes, spreadsheets, or half-remembered formulas. Sparky brings conduit bending, conduit fill, voltage drop, ampacity, breaker sizing, motor calculations, box fill, panel schedules, NEC reference notes, job notes, photo logs, and PDF reports into one focused mobile app. BUILT FOR ELECTRICIANS IN THE FIELD Sparky is designed for working electricians, apprentices, journeymen, foremen, contractors, maintenance techs, and electrical crews who need quick answers while the job is moving. Use Sparky for: • Conduit bend marks and bender setup • Offset bends, saddles, 90s, kicks, and multi-bend layouts • Conduit fill and conduit sizing • Voltage drop calculations • Wire ampacity and derating checks • Breaker sizing for continuous and non-continuous loads • Motor full-load amps, conductor sizing, OCPD, and overload values • Box fill calculations with conductors, devices, clamps, and grounds • Panel schedules, circuit loads, and phase balance • Job notes, local photo logs, and PDF exports • Searchable starter NEC reference content and citation chips CONDUIT TOOLS Select a bender, choose a bend type, enter the field measurements, and get live bend results. Sparky helps with common conduit work including offsets, saddles, stub-ups, kicks, segmented 90s, conduit fill, raceway sizing, and multiple-bend sequences. WIRE & LOAD CALCULATORS Calculate voltage drop, voltage at load, recommended wire size, ampacity, derating, breaker size, and motor values. Sparky gives you clear result cards with pass, warning, or fail states so important numbers are easy to scan. BOX FILL Check box fill quickly with conductor sizes, device count, internal clamps, equipment grounds, and cubic inch capacity. See remaining capacity and code-related context before the box becomes a problem. PANELS, JOBS & REPORTS Create panel schedules, add circuits, review connected load, check phase balance, attach panels to job files, add job notes, keep photo logs, and export PDF reports from the device. NEC REFERENCE WORKFLOW Sparky includes bundled starter NEC reference content for common calculator workflows. Result chips surface relevant code references so you can move from a calculation to context without losing your place. LOCAL-FIRST FIELD TOOL Core calculators, saved panels, job notes, photo references, and starter reference data work locally. Sparky is built for electrical rooms, basements, job trailers, and sites where signal is not guaranteed. ASO SEARCH TERMS IN REAL LANGUAGE Use Sparky as an electrician calculator, electrical calculator, conduit bender calculator, voltage drop calculator, ampacity calculator, breaker calculator, box fill calculator, wire sizing tool, panel schedule app, and field reference. WHY ELECTRICIANS USE SPARKY • Faster field calculations • Fewer repeated manual formulas • Cleaner panel documentation • Better inspection prep • One place for calculators, notes, photos, and reports • Designed for touch use on the jobsite • Light, dark, and system appearance modes IMPORTANT NOTE Sparky is a professional field aid, not a substitute for licensed electrical judgment, official code books, manufacturer documentation, engineered plans, local authority requirements, or inspection direction. Always verify calculations, code references, installation conditions, and equipment ratings before performing electrical work. SUBSCRIPTION Sparky Pro unlocks the full field toolkit. Pricing, free trial availability, renewal terms, and cancellation options are shown by Apple before purchase. Subscriptions renew automatically unless canceled in App Store account settings.
