MacCiv is the world's first Apple-native structural engineering app — a fast, beautiful finite-element tool for analyzing 2D and 3D frames right on your iPhone and soon on Mac Build a structure, hit Solve, and instantly read the internal forces and deformations: axial, shear, bending-moment and torsion diagrams, support reactions and deflected shapes. No clunky desktop software, no steep learning curve — just a clean, intuitive interface designed for the way you think. WHAT YOU CAN DO • Draw beams and columns, place supports (fixed, pinned, roller, hinge) and apply loads (distributed, point, trapezoidal, moments) • Solve full 3D frames with a real finite-element engine • Read coloured N / shear / moment / torsion diagrams drawn on the tension side, plus reactions and displacements • Switch between concrete, steel and wood members — each with proper material classes (EC2 / EC3 / EC5) • View your model as a true 3D solid, with steel shown as I-beams • See the seismic centre of mass and centre of stiffness for each structure BUILT FOR STUDENTS • Teaching mode: leave a load blank and MacCiv shows the answer as a formula (qL²/8, PL/4, …) instead of a number — perfect for learning statics • Metric and imperial units • Available in 9 languages NATIVE EVERYWHERE MacCiv is designed from the ground up for Apple platforms — it looks and feels right on macOS, iPhone and iPad, with full multitouch and a navigation cube for orbiting your model. FREE, WITH AN OPTIONAL UPGRADE MacCiv is free to use, supported by occasional ads. Prefer a clean, ad-free experience?
