MASTHAVE® is an app developed by renowned doctors that supports patients with mastocytosis in dealing with their disease. Mastocytosis is a rare disease in which mast cells accumulate in various body tissues. It affects around one in 10,000 people and severely limits the quality of life. Despite initial successes in the development of effective drug therapies, complete control of all symptoms is crucial for the well-being and lifestyle of affected patients. Take control of your mastocytosis: In just a few minutes a day, you can record your symptoms and their impact on your quality of life. Work with your treating doctors to track your disease progression, how you respond to your therapy and how it can be optimized for you. To do this, it is important that you record your data continuously over a longer period of time with MASTHAVE®. The data you collect can also help researchers to better understand mastocytosis. Your results will thus contribute to the development of new treatment options. From now on you are no longer alone - MASTHAVE® supports you at all times! Are you a doctor?
