ScientificVecta
A scientific calculator that shows its work
In development Android
A full scientific calculator - trigonometry, logarithms, statistics, complex numbers, matrices and a function grapher, plus a calculus workspace - built for people who want to see their work, not just an answer. Every calculation shows how it was reached, so you can check the steps instead of trusting a black box. Deterministic engine, verified constants pack, runs offline in 25 languages. No accounts, no network, no tracking.
What it does
Results with their working shown
Every calculation shows how it was reached - reasoning you can review, not just a bare number.
Deterministic and verified
A deterministic engine and a signed constants pack that is integrity-checked before it opens.
Private by default
Runs entirely on your device in 25 languages, including full right-to-left. No accounts, no ads, no trackers, no network calls.
Questions
Does it work offline?
Yes. The engine and its constants run on your device; it never makes a network request.
What's free versus paid?
The core calculator - every function and result - is free. The interactive calculus studio is an optional one-time unlock, or part of the all-access membership.
The CoreVecta promise
Like every CoreVecta app, ScientificVecta works fully offline, anchors its answers to verifiable sources, and sends nothing anywhere. There is no server to receive it. Knowledge packs state their review status on their face, and packs touching high-stakes domains are reviewed by credentialed professionals before they're labeled ready.
