What we're building
Every app starts with a real, personal need — something we or our family actually wanted to use. No filler, no fluff.

App 01
CCCR
Confession & Catechism Research — a study companion for Christian theology.
CCCR helps pastors, students, and curious readers explore the historical confessions, catechisms, and the writings of the Church Fathers without drowning in PDFs. Ask a question in plain English and CCCR retrieves the relevant passages from the primary sources, with citations you can verify yourself.
Built on a retrieval-augmented search layer over the Reformed and patristic canon, designed for people who care about getting the answer right.

App 02
Rastfuchs
The German Autobahn rest-stop guide — built for families who actually have to use them.
Rastfuchs maps every Raststätte across the German motorway network with the details that matter on a long drive with kids: playgrounds, baby-changing rooms, kid-friendly menus, accessible toilets, and honest reviews. Filter by what you need, get there before the meltdown.
Over 1,800 stops indexed today. Originally built for our own family road trips — now public, free, and constantly being added to.

App 03+
What's next.
More apps are in the pipeline — each one solving a real problem we (or our family) actually have.
Stein Street Solutions exists because building a single app is satisfying — but building a portfolio of small, sustainable products that genuinely help people is the goal. Every new project gets the same treatment: real need first, AI-assisted engineering, and a clean home page right here on the studio site.

AI-assisted development
Every app is built with AI handling the engineering. It lets a non-technical founder focus entirely on product vision and what actually matters to users.
Built to last
We don't chase trends. Each product solves a real, enduring problem — something people will still need in five years, not just something that's fashionable today.
Community-first
Free core apps, honest monetization, no dark patterns. We build with real users from the start and stay close to feedback throughout.
German roots, global reach
Based in Sachsen, built for the German market and beyond. Localisation, data privacy, and DSGVO compliance are first-class concerns — not afterthoughts.
About
A studio from Sachsen
Stein Street Solutions is an independent app studio based in Heidenau, Saxony, Germany — the home of CCCR, Rastfuchs, and the apps to come. We build software we'd actually want to use ourselves — tools for research, family life, and the everyday.
Our development process is unconventional: we rely heavily on AI to handle engineering, which lets a non-technical founder focus entirely on product vision, UX, and what genuinely matters to users.
What started as a hobby is becoming a serious effort to build useful, sustainable software. Each app is an honest attempt to solve something real — and to make something we're proud of.
