Applications for patients with heart problems

Easier work for cardiologists

Communication (not only) via videocall

Saving time

Challenge is an app for cardiologists and their patients with heart problems. Its main function was to provide quick and easy communication between the two sides. MUDr. Václav Durdil, a cardiologist from the hospital in Motol in Prague, ordered the app with the intention to gradually expand it not only across the country.

  • Easy way of communication between doctors and patients
  • Video call option
  • Saving time
  • Mobile and web application


Communication between doctor and patient is enabled either by chat or video call. A very useful feature is the „automated conversation“. This offers the patient questions that are pre-selected by the doctor himself, and the answers show the most likely diagnosis. The patient will quickly find out what is bothering him and save himself and his doctor time 

Of course, each patient enters details of his or her health status at registration, including previous medical interventions, medications and other necessary information. This way, the doctor always has everything important in one place and knows what he or she is working with.  

We have developed the app in web and mobile versions. While developing the web app, our programmers worked with VueJS for the front-end and .NET Core for the back-end. The mobile, which is available on both Apple and Android devices, was created using the Xamarin framework.
