What Accumath is
Your machine, offline
You install it on your computer. You work offline. You keep your files. Air-gapped by design: no network call to stay licensed, no cloud license server, no black-box server heuristics guessing at your math.
The same answer, everywhere
Numeric work runs on SoftFloat — software floating point — so the same equation with the same inputs produces the same bit-identical results on every computer. That is not “close enough.” That is the same answer.
One license, for life
One lifetime license belongs to one person. All current and future updates and upgrades are free for life. Move it to a new machine whenever you like — good for one machine at a time.
Why Accumath instead of the usual options
Reproducible numbers
SoftFloat bit-identical results across machines. Publish a result and anyone can reproduce it exactly.
True offline use
No license server and no required network. It works in the lab, in the field, on a plane.
Not a wrapper stack
Pure Rust throughout — not a thin shell over C or Python foreign math runtimes. One controlled stack from calculation to notebook.
Honest failure
When something cannot be done, Accumath says so instead of guessing. Malformed input gets an honest error, never a silent wrong answer.
Simple ownership
One door, lifetime, the license belongs to the person. No subscriptions, no tiers of entrapment.
Useful on day one
Ships with about half a million unique parsed equations, already typed for search and use — not a library you have to build from scratch.
Where the build stands
Estimated ship date: January 2, 2027 · updated 2026-10-02
Every built item has tests, and those tests pass. The list is public and the record stays honest.
Where it runs
Linux
Debian-based (Debian, Ubuntu, Pop!_OS), Fedora-based (Fedora, RHEL), and Arch-based.
Windows & macOS
Desktop coverage on both, pursued after the core build.
FreeBSD
On the version 1 ship list with the rest of the desktop targets.
Install on your own machine. Work offline. Accumath is pure Rust — the goal is broad desktop coverage, not one vendor’s OS.
Own it for life
Planned direct, per-seat pricing. Each licensed user keeps Accumath for life — including after graduation — with updates, upgrades, and later versions included. No recurring subscription.
After version 1
The work does not stop at launch: keep expanding Accumath, keep maintaining it, keep adding to the equation library — then build AccuMathLab, the next product. Your license covers it: if you already hold an Accumath license — early supporter or later — you get Accumath updates and AccuMathLab when it ships, under the same lifetime license you already bought.
