The App Review Guard acts as an intelligent, documenting and self-verifying “middleware”. This intermediate application offers significant advantages, as it is compatible with a variety of systems. The App Review Guard operates as a system for allocation in ticket systems and CRM-systems which results in reduced workload.

Within regular intervals the App Review Guard checks the applications, as agreed individually with our customers. In general, the test is carried out once an hour. The App Review Guard documents all messages that are published via the app stores.

These messages are first documented in a central system and subsequently forwarded as notification to the medically and technically trained employees of Cross4Channel GmbH. These manually check the messages for pharmacological relevance and decide on the further obligation to report to the sponsors.

As specialists in digital healthcare marketing, we know that data protection is a top priority, especially in the pharmaceutical environment for pharmaceutical companies and patients. We have made it our mission to set the highest safety standards. As a result, all our data centres are located in Europe, are ISO 27001 certified and thus conform precisely to the German Data Protection Act.
