Implementation Guide Untire Diga

This document aims to describe the interoperable data export format used by Untire (a product of Tired of Cancer BV) as DiGA (Digital health applications) in Germany.

Scope and Disclaimer

This document describes the interoperable data export of Untire as a Diga in Germany. The data export format explained here follows the same basic principles and applies to all present and future DiGA products developed by Tired of Cancer. For interoperable export, Untire relies on the FHIR® standard published by HL7®. Untire follows the openly published FHIR® Specification v4.0.1: R4 without further profiling and generates a valid json file as export. The JavaScript Object Notation (JSON) is a standardized, open, text-based format for displaying structured data.


This implementation and its specifications are intended to enable other manufacturers of digital products to further process a patient's data recorded in the Untire® app through a machine-readable, interoperable format.

Data Export

In the settings page of each product, patients can export relevant data as a single json file. For this purpose, the FHIR® Bundle resource is used to contain the FHIR resources Patient and Observation. Details can be found here
