About Rafter & Framing Calc: BuildX

Rafter & Framing Calc replaces cheat sheets and clunky calculator apps with something built for the jobsite: fast fraction-based input and instant rafter, stair, and framing math you can read at a glance. Pay once, own it forever — no subscriptions. Built solo by an iOS designer who got tired of ugly trade apps.
