In-house software, built carefully.
Here we build lean tools that close specific gaps in practice and SME workflows — uncompromising on data protection, simple to use. The range currently comprises four products.
Four tools for practice and office.
They reflect how we work: solve concrete problems, protect data consistently, keep the UI focused on what matters.
Time tracking for SMEs
Multi-tenant web app with live stopwatch, automatic statutory break (ArbZG), shift planning, leave workflow and a DATEV payroll interface. First pilot is running in a dental practice.
- ArbZG break: added, not hidden
- Corrections with audit trail
- DATEV payroll import/export
- Self-hostable (Docker Compose, Postgres)

- Public-token mode without account
- White-label under your own brand
- DPAs & privacy templates included
Objektlotse — claims management
Multi-tenant (n:m) portal for insurers, brokers, property managers and HOAs — with strict data separation, a public reporting link, e-mail-to-case and a native iOS app. Self-hosted or managed.

Kundenbuch — lightweight CRM
All business contacts and every interaction in one place: calls, emails, notes, documents and follow-ups in each customer's history. A native Apple app synchronised via your own iCloud, no server of its own.
- Automatic entry for calls and emails
- Import from Apple Contacts — business details only
- Follow-ups with a daily overview
- Demo on request
And one program just for you.
A side project beyond the B2B tools — for people who write on the Mac. (Only in German for now.)
Feder — a writing app for the Mac
A calm writing environment with a book-like editing surface and a library for ideas, projects and journal entries. Markdown at the core — your texts stay as plain .md files on your Mac, no database, no cloud.
