FrameCalc - physics compute with plots
Instant computed math and physics parameters in 10 seconds.
FrameCalc - physics compute with plots launched on September 5, 2026.
What it does
Browser calculators for special-relativity kinematics, teaching simulations, fusion, and dozens of libraries for solving hard problems across physics and mathematics. Copy LaTeX, compute data, simulate. Pro model adds PDF, CSV, and code export.
Browser calculators for special-relativity kinematics, teaching simulations, and standard fusion formulas. Copy LaTeX. Pro adds PDF, CSV, and code export.
FrameCalc is a browser toolkit for special-relativity kinematics, teaching simulations, and standard fusion formulas — with plots and LaTeX copy. Calculators and simulations are free. Pro is for PDF, workspace, sweeps, dataset export, and code. Collisions, decays, Lorentz, Compton — free, with LaTeX copy. Kepler, Schwarzschild, TDSE, Ising — teaching-resolution playback. Bosch–Hale ⟨σv⟩, Child–Langmuir, Coulomb barrier, labeled yield estimate. PDF, workspace, sweeps, dataset export, CAS snippets, course-pack JSON, history. Teaching-resolution time-stepping with on-screen diagnostics. Bosch–Hale reactivity, Child–Langmuir current, Coulomb barrier, and a labeled yieldfrom framecalc.site

Its basically just an aggregation of various commonly used calculators and unit convertors. Link: https://www.calcverse.live Tech Stack: Next, React, Typescript, shadcn UI, Tailwind CSS Would greatly appreciate your feedback on the UI/UX and accessibilty. I struggled the most with navigation. I've added a search box, a sidebar, breadcrumbs and pages with grids of cards leading to the respective calculator or unit convertor, but not sure if…
