Every calculator a contractor needs, in ONE offline app. Pay once, own it for life. No five separate apps, no per-trade packs, no subscription trap. TradeCalc runs 100% on your device. It works in a basement, a crawlspace, or a job trailer with zero signal, because it never needs the internet. No account, no login, no data leaves your phone. Open it, run the numbers, and get back to work. While the big-name calculators moved to monthly billing and lock each trade behind its own paid pack, TradeCalc gives you the whole toolkit for one Lifetime price. Every calculator also estimates the materials AND the cost, so you can quote on the spot. WHAT IS INSIDE Construction Math - Add, subtract, multiply, and divide in feet, inches, and fractions - Convert between feet-inches, decimal feet, and metric - Built for framing, layout, and takeoffs Electrical - Ohm's Law (volts, amps, watts, resistance) - Voltage drop over a run, so you size the conductor right - Wire size and ampacity based on NEC 310.16 - Raceway fill at the 40% rule Plumbing - Pipe sizing for supply and drainage - GPM flow so fixtures get the water they need Coverage and Materials - Tile, flooring, paint, and drywall - Enter the room, get sheets, boxes, gallons, and waste allowance - Instant material count plus cost Concrete and Asphalt - Slab and footing volume in cubic yards or meters - Asphalt tonnage for paving and patching - Bag counts, truck loads, and total cost HVAC - Air conditioning tonnage for a space - CFM airflow for duct and register sizing Every result is built to be read fast and trusted on site. Switch units, change the price per unit, and the material and cost totals update with it. NO HIDDEN COSTS, NO DATA COLLECTION Everything runs on-device. There are no ads, no trackers, and no analytics. We do not collect, sell, or share your data, because none of it ever leaves your phone. The Lifetime unlock is a true one-time purchase, not a disguised subscription. WHO IT IS FOR Electricians, plumbers, HVAC techs, carpenters, masons, pavers, remodelers, estimators, and DIY pros who want one dependable tool instead of a phone full of single-purpose apps.
