About Elfie

Elfie has the ambitious mission to save millions of people every year. Our vision is to provide a holistic and gamified solution to chronic diseases, the silent killers of our generation.

25% of all people die from a chronic disease (hypertension, diabetes, cholesterol). The good part is that it could be avoided if people followed their doctor's prescription and lifestyle recommendations. The sad part is that they don't due to lack of awareness of danger, unwillingness to change lifestyle,  and costs to follow treatment (lifelong). 

Elfie is a chronic disease management application that gamifies self-monitoring and supports patients across the world. It is promoted by 10,000s doctors and endorsed by healthcare leaders.
