StoichioMate

SiteForce Mate is a fully offline engineering pocket toolkit built for construction site foremen, junior engineers and field supervisors who need quick, reliable estimates without leaving the job. It bundles a curated set of real structural and material calculators into a clean, distraction-free interface that works the moment you open it. No account, no internet connection, no advertising and no subscription. Calculate bending moments, shear and support reactions for simply supported and cantilever beams. Estimate column axial capacity, check shallow foundation bearing against the soil characteristic value, and compute concrete volumes with a mix-ratio breakdown. Quickly find rebar weight, cutting length and stirrup lengths for common diameters; estimate slab volumes and brick or block quantities for masonry walls; and evaluate sloped pit or trench excavation volumes using a prismatoid formula. A built-in unit converter handles forces, stress, length, area and volume, while the Library tab keeps essential reference tables for material unit weights, rebar mass and concrete grades close at hand. Every calculation can be saved locally for later review. Dark mode is fully supported. Note: results are quick on-site estimates only — formal structural design must follow the applicable national codes and qualified professional review.
