Web, mobile and internal apps

Apps for real work. Not for demo.

We develop focused applications that remain fast, clear and maintainable in daily use.

When standard software bends the process.

A custom app is worthwhile where devices, roles, data, or workflows need a suitable interface.

Web

Portals and specialized applications for browsers and large workspaces.

Mobile

Scanners, camera, files, and offline data directly at the site of use.

Internal

Tools that sensibly connect existing systems and team workflows.

Three levels determine the success.

Features alone do not make a good app. Core value, real-world use, and operations must work together.

Core benefit

MVP with clear core benefit

A focused feature set shows early on whether the app works in everyday use.

  • Define core task
  • Make process tangible
  • Integrate early feedback
Real usage

Usage under real conditions

Clear states, short paths and robust offline capability for real work situations.

  • Consider device context
  • Catch offline cases
  • Keep user paths short
Product Operations

Reliable operation

Reproducible builds, tests, telemetry and updates make the solution reliable.

  • Secure builds and tests
  • Make errors visible
  • Roll out updates predictably

Two product receipts from the field of application.

Technology follows usage and operation.

Platforms are oriented towards devices, teams, data flows, and life cycles.

  1. User interfaces

    Tailored to device, usage and team.

    • Angular
    • .NET MAUI
    • Kotlin
    • React Native

  2. Synchronization

    Data flows reliably between the app and connected systems.

    • REST
    • GraphQL
    • WebSocket
    • MQTT
    • SQLite
    • PostgreSQL

  3. Operation

    Releases and error cases receive a defined path.

    • CI/CD
    • E2E tests
    • Telemetry
    • Signing
    • Rollback

From Use Case to Operation.

Short feedback keeps the product close to the people who actually use it.

  1. Refine Use Case

    Users, environment, and core task are made concrete.

  2. Make the pilot experience tangible

    A clickable workflow provides early feedback.

  3. Build the product to be robust

    Data, interfaces, and edge cases are integrated.

  4. Roll out and operate

    Release, monitoring, and further development get a clear path.
