Precision before speed.
Every feature comes from a clear intent. No bloat, no rush — only what truly holds up.
Qorvano° — Software with intent
We build software that steps aside — so your thinking has room.
Qorvano° is an independent software studio based in Nottuln (Münsterland region, Germany) that builds apps, websites and SaaS products — for people and teams who don't want to confuse the tool with the thought. Quiet in tone, clear in structure, dependable day to day.
Principles
Three lines that carry every decision.
Qorvano° is not a platform that does everything. It is a small studio with a stance that shows up in every line of code.
Your data stays with you.
No trackers. No background analytics. What happens on your device stays on your device.
Quiet surfaces.
Software that does not push itself to the front. Clear typography, generous emptiness, considered motion.
Apps
For tools that sit in the hand, daily.
Our apps are self-contained. Offline-capable, data-sparing, and crafted to still feel good the tenth time you open them.
New
Numeris
Scientific calculator · 2D / 3D plotter
A precise calculator for daily work, study and engineering. Live LaTeX preview, symbolic derivatives up to 5th order and 3D surface plots — no tracking, offline-capable.
Web
Lineon
String-art generator · iOS / Android / Web
Photo in, printable build guide out. Lineon computes the wrap order for a string-art piece and ships it as a PDF with materials list, 1:1 layout diagram and wrap table. Web variant runs straight in the browser.
SaaS
A stance on SaaS — before there is any.
Whether we will build SaaS at all is not decided. The conditions under which we would, are.
Technical foundation
Tools in service of the work.
We pick technology for longevity, not trend. Every choice can be reasoned about.

A small studio. With a signature.
