WITTE App Project

WITTE Projektmanagement GmbH manages complex construction projects nationwide, relying on a close integration of project management, controlling, and BIM-supported planning.

To provide clients with up-to-date insights into costs, progress, and status reports at all times, Hitabis collaborated with WITTE to develop a native app for iOS and Android that synchronizes data from the internal CRM.

The middleware, based on Ruby on Rails and MariaDB, aggregates and harmonizes the CRM data, automatically processes key figures and cost figures, and transfers them to the app via secure REST interfaces.

The app, built using React Native, displays project-specific dashboards, cost timelines, graphical status reports, and detailed pages for buildings, trades, and partners.

Hitabis is also responsible for the container-based operating platform, automated deployments in test, acceptance, and production environments, as well as SLA-based operations, including monitoring, incident management, and change management.

Since its launch in 2020, the “WITTE App” has been available in app stores and is continuously being expanded with new features and adapted to updated interfaces.

Key features of the project:

• Automated ETL processes from WITTE-CRM
• Role-based REST APIs for building owners and project managers
• Graphical representation of project status values and budget trends for mobile devices
• UX/UI design that perfectly matches the look and feel of the client’s corporate design
