FK is a free iPhone application developed by Zorginstituut Nederland, designed to provide easy access to the complete Farmacotherapeutisch Kompas (Pharmacotherapeutic Compass). This comprehensive guide, also available online, offers a wealth of information on medications, indications, groups, and general texts.

With the 2017 website update, the FK now includes not only medication texts but also indication texts with a handy step-by-step plan, group texts, and general texts. The documents are interconnected with links, and additional reliable information from other organizations is provided. Users can easily find texts through an advanced search function and compare them to each other.

One of the standout features of FK is the ability to access the medication texts offline, making it particularly useful for healthcare professionals such as general practitioners and hospital staff. The application is updated every two months, ensuring that the information remains up-to-date and reliable.
