Support and privacy for each application published here. Every one of them runs entirely on your own device.
Compressible flow, solved and written up. Shocks, nozzles and duct flow, each relation shown beside the number it produced.
Sections, shear, torsion and Mohr's circle -- build a section, load a beam, and watch every screen redraw as you drag. Offline, no account.
Convert video without waiting. Hardware-accelerated on Apple silicon, and nothing leaves the machine.
Journal figures from your data, reproducible to the pixel.
Beams, deflection and buckling -- forty-five screens, each opening on a worked example and redrawing as you type. Offline, no account.
A local LaTeX editor with live preview -- the typesetting engine runs on your device, not a server.
Steam tables, cycles and exergy -- states from the IAPWS-IF97 industrial formulation, cycles drawn on live T-s and p-v diagrams. Offline, no account.
Classical electrodynamics, nineteen modules from point charges to the relativistic transformation of fields. Every relation shown beside the number it produced, in SI or Gaussian. Offline, no account.
