90+ SYMBOLS, DRAG AND DROP US symbols with NEC terms, or international IEC 60617 symbols. Switch at any time. ⢠Power, switches, lighting: receptacles, switches, dimmers, ceiling, recessed and emergency lights. ⢠Fire and security: smoke, heat and CO detectors, pull stations, horns, motion sensors, cameras. ⢠Data, heating, appliances: data and TV outlets, Wi-Fi, heaters, ovens, washers, dryers. ⢠Energy and panels: EV chargers, solar, safety switches, meters, and a custom symbol you name yourself. ⢠Drag one out of the palette and it lands under your finger. Rotate in 90° steps, add a label, circuit and notes, resize one symbol or all. CREATE OR IMPORT A PLAN ⢠Import a PDF, or a photo from your library or from Files. ⢠Or, scan several pages with your camera and each one becomes its own plan. ⢠Or, scan real-life rooms in 3D with your iPhone Pro or iPad Pro, and get the floor plan drawn for you instantly. ⢠No plan? Draw walls, doors and windows yourself from a blank template. RUN THE CIRCUITS ⢠Tap a symbol, tap another, and a smooth curved run joins them. ⢠Runs stay attached: move an outlet and the wire moves with it. ⢠Pick the circuit as you draw. Every circuit gets its own color, and it is the same color in the editor, in test and on the PDF. ⢠Eraser mode, delete a symbol and its runs go with it, and undo/redo while you work. CHECK YOUR WORK ⢠Check: traces the wiring out from every panel and flags anything unpowered or left dangling. ⢠Simulate: tap switches on and off and see which lights come on. ⢠Loads: per-circuit VA and amps (at 120/240 V with US symbols) against the breaker rating you set. These are indicative aids for catching mistakes on a drawing. They are not certified design or verification calculations, and they do not replace inspection, testing, certification or the electrical code that applies to your job. LEGEND AND PDF ⢠A legend of every symbol type and circuit used is built for you and added to every export. ⢠Export a PDF in the plan's shape, or on US Letter or A4, or save it as an image. BUILT FOR THE JOB SITE ⢠Lose signal mid-job and keep working. Changes save on the device and sync to your account when you are back in coverage. ⢠iPhone: turn it sideways and the plan fills the screen, tools on side rails. ⢠iPad: a symbol panel beside the plan. SHARE WITH THE CREW ⢠Invite a teammate with an 8-character code and they can open and edit the project's plans on their own iPhone or iPad. WHO IT'S FOR Independent electricians and crews doing residential and commercial work: rewires, rough-in, additions, panel changes, build-outs. Anyone who has to hand a customer, a builder or a general contractor a drawing showing where the outlets, switches and lights actually went. QUESTIONS OR IDEAS Contact support or request a feature from the account menu. You get a fast reply, straight from the developer. Sign in with Apple or Google.
