About us
A software house for AI and app development.
Behind appDev is a team that has been building software for over 15 years for organisations with high demands on data protection and auditability. That background shapes how we build AI. Access control, clean integration and auditability are the starting point from day one, for start-ups just as much as for large enterprises.

Areas of expertise
Where our depth lies.
Native apps for iOS and Android
Our core strength, from the first version to apps running in production with high user volumes.
AI, RAG and document processing
Assistants with source citations, receipt recognition and AI features, connected to your systems.
Health, ePA, FHIR and telematics
Integration with the telematics infrastructure (TI), FHIR data models and experience from live ePA applications.
Web, backend, cloud and integration
Scalable backends, portals and connecting AI to established ERP and legacy systems.
Finance and insurance
Software built for the auditability, traceability and security these sectors expect.
Industry, retail and logistics
Applications with high demands on availability, data quality and offline operation.
Team
The team.
At appDev you work with permanently employed senior engineers. The people who build your project are the same people you talk to, from the first idea to hand-over.
In the end you take over working software along with its documentation and can keep working on it yourself at any time. Several people on the team bring proven experience in health, telematics, FHIR and demanding regulated processes. The team is employed in Germany and German-speaking.
