• Postpartum Depression: PPD Act is a new app-based study that will use genetic testing to better understand why some women are impacted by postpartum depression by examining the genetic makeup of those with the condition. Led by the University of North Carolina School of Medicine and the international Postpartum Depression: Action Towards Causes and Treatment Consortium, PPD Act will offer study participants access to a “spit kit” from the National Institute of Mental Health.
• Cardiovascular Disease: Developed by Stanford Medicine, the MyHeart Counts app will use genetic data from existing 23andMe customers to help determine predisposition to heart conditions and measure how a participant’s activity and lifestyle relate to cardiovascular health. By studying these relationships on a broad scale, researchers hope to be able to better understand how to keep hearts healthy. 
• Asthma: The Asthma Health app, designed to track symptom patterns in an individual and identify potential triggers for these symptoms, will use genetic data from 23andMe customers to help researchers better understand ways to personalize asthma treatment. Asthma Health is designed by the Icahn School of Medicine at Mount Sinai and LifeMap Solutions.

Researchers continue to adapt ResearchKit and build on the framework by contributing new modules that bring exam room medical tests to iPhone apps. Key contributions include the ability to study tone audiometry; measure reaction time through delivery of a known stimulus to a known response; assess the speed of information processing and working memory; use the mathematical puzzle Tower of Hanoi for cognition studies; and conduct a timed walk test.
