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.
