BendRight Pro is a fast, offline NEC toolkit for working electricians. Nine professional tools in one app — free to download, no account, no data collection. Every calculator runs entirely on your phone, even in a basement or a dead-signal job site. WHAT'S INSIDE • Conduit Bending — stub-ups, back-to-back, offsets, parallel and rolling offsets, kicks measured from the back of the 90, 3- and 4-point saddles, corner bends, and segmented 90s. Pick your bender shoe (Ideal, Greenlee, Klein presets) for exact radius-corrected math, or use classic field multipliers. Every bend gets a live diagram with center-of-bend marks, a layout bar with stacked fraction dimensions from the end of the pipe, and an illustrated how-to-bend guide. • Level — turn your phone into a digital angle level. Zero it on the pipe, pick a target (10, 22.5, 30, 45, 60, 90°), and watch the live to-go readout count down to "on target." Hold freezes the reading. • Footage & Inch Math — a tape-measure calculator with exact fraction math in eighths, plus a regular four-function calculator that sends its answer straight into the tape math. Add feet-inches-fractions, multiply a piece length by a count, split a span into equal marks. • Commercial Load Calc — lighting, receptacle, motor, HVAC, kitchen, and sign loads with demand factors. Sizes the service and shows the governing constraint on every conductor. • Residential Load Calc — standard and optional methods (NEC 220.82) side by side, so you can pick the smaller legal service. • Conduit Fill & Pull — fill percentage against Chapter 9 Table 1, jam-ratio warning, and pull-tension flags. EMT, RMC, IMC, PVC. • Voltage Drop — one-way and round-trip, copper or aluminum, with pass/fail against your chosen percentage. • Code Reference — 60+ plain-language summaries of the most-used 2023 NEC / 2025 CEC articles with instant search. Original wording; links to NFPA's free official text. • Jobs + Quick Estimator — track jobs and build a material-and-labor takeoff from ~40 assemblies with editable prices, state wage presets, and difficulty factors. Takeoff to suggested bid in one tap. BUILT FOR THE FIELD • Every calculator is 100% offline. The app makes no network connections at all — no login, no cloud, no tracking. • Dark mode for pre-dawn starts; follows your phone's setting. • Your projects and jobs are saved on-device and stay there. • Big tap targets and numeric keypads — usable with gloves and one hand. WHO IT'S FOR Journeymen, apprentices, estimators, inspectors, and shop owners who need trustworthy numbers fast, on a phone that keeps working where there is no signal.
