What we build.

We build native-feeling apps for iOS and Android with Flutter: one codebase, two stores, full platform integration (haptics, motion, accessibility, dark mode, Dynamic Type). Our design approach is quiet and restrained — the app should be the tool, not the stage.

Our first public app is Numeris: a scientific calculator with live LaTeX preview, symbolic derivatives up to the 5th order and 3D surface plots. It runs fully offline, talks to no server, tracks nothing. We bring the same stance to client work: privacy-by-design, one-time purchase or clearly agreed licence, no dark patterns.

Typical use cases: standalone tools, companion apps for SaaS products, B2B applications with strict requirements around data minimisation or offline capability.

We build websites with Astro and statically generated HTML: short load times, clean document structure, strong accessibility, stable Core Web Vitals. Typography is the first, not the last, design decision.

Privacy is a design principle: no analytics by default, no external tracking, no Google Fonts. Where trackers or third-party services are genuinely needed, we document them openly — and gate them behind explicit opt-in where the law requires it.

This very site is a reference: static, bilingual, self-hosted fonts, light and dark modes, no cookie banner.

For SaaS and bespoke web applications we use a lean stack of Python/Flask, SQLAlchemy and a classic Postgres database, running on servers in Germany. The result is software that is straightforward to maintain and reason about — not frameworks that celebrate themselves.

Our own SaaS line is still early; we don't announce what we can't reliably ship. For our clients, however, we already build today: internal tools, portals, domain-specific applications in healthcare, trade or education contexts.

If a spreadsheet has long since become a team's working tool and is now hitting its limits, that is our typical starting point.
