We make a small number of medical applications, slowly, on purpose.
Medicon Applications is an independent studio in Copenhagen. We have been releasing medical apps for iPhone, iPad and Mac since 2008. Each application is a small, focused tool — built to answer a single clinical question, well — and released only when it earns its place.
We are a doctor and a designer. We do not raise capital, do not advertise, do not subscribe-gate, and do not run analytics in clinical software. The studio is funded by the hospital work of the people who run it — which keeps the apps honest, and keeps them free.
