Rafter & Framing Calc: BuildX

Why rent a calculator? you have a better and smarter option. Pay $24.99 once and unlock all 15 tools forever. No subscription, no upsells, no games.

BuildX replaces your notepad, your regular calculator, and a stack of separate apps with 15 trade tools built for real jobsite math — stairs and IRC rise/run checks, stud spacing, rafters, slope and grade, concrete and footing/rebar, roofing, drywall, fencing, board feet, cut-list optimization, and more.

Enter measurements the way the trade actually works. Type 5' 6-3/8" directly — no converting to decimal, no second app to check your math.

Pay once. No subscription. One purchase, every tool, every future update.
