StructCalc was created to put professional-grade construction math in your pocket — fast, accurate, and fully offline.
Every carpenter, framer, and contractor knows the frustration of stopping work to double-check a measurement or dig out a construction calculator. StructCalc replaces the paper, the guesswork, and the back-and-forth.
We believe the best tool is the one that gets out of your way. Clean inputs, clear results, no distractions. And because job sites don't always have signal, everything works offline.
Your projects live on your phone, not in a cloud. No account, no uploads, no worries about connectivity.
Every calculator was designed with real-world framing, roofing, and stair-building workflows in mind.
We add tools and refinements based on what users actually need on the job. Feedback drives every update.
