mpolyco is a complete, offline engineering toolkit for polymers, composites and mechanical engineering — materials data, calculators, simulations and a full reference library, all running on your device. No account. No internet. Nothing collected. Built for students learning the field and engineers who need a trustworthy answer fast: every model is validated against textbook and literature reference values, and every material property ships with its provenance. WHAT'S INSIDE • Calculators — classical laminate theory (ABD stiffness, engineering constants, per-ply stresses, first-ply failure), micromechanics (rule of mixtures, Halpin–Tsai), beams & pressure vessels, Mohr's circle, and a unit converter. • Simulations — viscoelastic creep & relaxation (Maxwell, Kelvin–Voigt, SLS), failure envelopes, cure kinetics, stress–strain, fatigue, DMA, WLF shift, step-growth polymerisation, Fickian diffusion, and pipe flow & drag. Analytic curves, computed live as you type. • Materials database — polymers, fibres and composite systems, each property sourced and citable. • Periodic table — every element's electron shells and the part it plays in polymers and composites. • Engineer's Handbook — the formulas that run mechanical engineering: beams, vessels, gears, springs, heat transfer, vibrations, torsion, columns, tolerances, fasteners and constants. • Basics & glossary — physics, chemistry and maths explained in plain language, with every symbol defined. New to the field? Start here. PRIVATE BY DESIGN mpolyco has no server and collects nothing — no tracking, no analytics, no account. An optional profile stays only on your device and is never uploaded. Everything works with Airplane Mode on. WORKS EVERYWHERE Native on iPhone, iPad and Mac, with a home-screen widget, Spotlight and Siri search, and an on-device "Explain simply" helper on the latest devices. Export any calculation as a report and email it to yourself or a colleague. Free — no ads, no in-app purchases. Privacy Policy: https://mpolyco.com/privacy Support & questions: hello@mpolyco.com

Verdict
The clearest difference is ads: mpolyco at none against CompositesAI's shown. CompositesAI's advantage is update cadence (every 9 days vs monthly) and iOS requirement (14.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.
