Users also have the ability to opt-in to a research study, which will provide researchers with important data about this rare disease. There will be optional, once-a-month surveys that ask users about how sarcoidosis affects their lives, paired with passive data collection from background health apps, such as step-tracking. The insights gained from this study may help raise awareness of the impact of sarcoidosis, with the ultimate goal of improving quality of life for people with this disease.
