FieldDojo is the jobsite in your pocket. Walk a room in 360°, pin what you saw to the wall, run the trade math on the spot and hand the client one report when you leave. WALK THE JOB Capture every room as a 360° panorama. Drop numbered hotspots on the walls for notes, linked rooms and the calculations that belong there. The whole walk lives in one project, so the kitchen, the panel and the crawl space are a tap apart. The walkthrough is part of FieldDojo Pro. PIN THE PLAN Put the floor plan next to the rooms. Every room gets a numbered pin on the plan, so anyone opening the project knows where they are standing. 57 CALCULATORS, 4 TRADES Construction: concrete volume and bags, board feet, stud count, drywall sheets, roofing squares, roof pitch, rafter length, stairs, decks, fences, tile and grout, flooring, paint, gravel, pavers, retaining walls, insulation, carpet, mulch, CMU walls, feet and inches, unit conversion. Electrical: wire size, voltage drop, conduit fill, conduit offset bends, breaker size, electrical load, dwelling load (NEC 220), motor FLA, ampacity derating, ground wire size, transformer kVA, three-phase current, Ohm's law, power conversion. HVAC: BTU load, heat loss, duct sizing, tonnage, CFM per ton, air changes per hour, refrigerant charge, SEER savings. Plumbing: pipe sizing, gas pipe size, drainage slope, flow rate, water pressure loss, fixture units (DFU), water heater sizing and first-hour rating, septic tank size. Imperial and metric. Set your material prices once and the material calculators carry a cost estimate. KNOW WHY Every calculator has a reference page with the formula and the code notes behind it, down to the NEC table or the ACI section, so you can show the inspector where the number came from. ROOM TO REPORT Everything from the walk lands in one project: rooms, pins, notes and saved calculations. Export a calculation as text or CSV from the share sheet. BUILT FOR THE SITE The calculators need no account. An account keeps your projects on your phone; they leave it only when you choose to sync. Everything works without signal. FIELDDOJO PRO Every calculator works without a purchase; every account gets one project for its saved calculations. FieldDojo Pro adds the 360° walkthrough (rooms, floor plan and pins), unlimited projects, sync across devices (phone on site, desktop in the office), backup of every calculation you have run, branded PDF reports with your company details, and sharing a walkthrough by link so the client opens it in a browser with no app. Pro is available as a subscription or a one-time lifetime purchase. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
