Heart & Brain app for iPhone and iPad

This app is a clinical study that uses iPhone to discover irregular heartbeat and stroke at an early stage and maintain your quality of life. iPhone, Apple Watch, and other portable devices have sensors that can collect health-related data. This research study investigates whether we can detect disease by analyzing data acquired by mobile devices. We hope to assess whether the iPhone and wearable devices like Apple Watch can be used as early diagnosis tools. If so, these devices might be able to prevent irreversible strokes and maintain quality of life.

Data collection
This app uses a framework called "ResearchKit" by Apple. In the past it was common for participants in medical research to come to a hospital or research lab. But using iPhone, which is carried by many hundreds of millions of people around the world, it is possible for participants to participate freely in the clinical research, and enabling the creation of efficient medical data. Using this system, you will answer a questionnaire regarding irregular heartbeats, the stroke risk, and quality of life. There are also a variety of advanced sensors installed in the iPhone and Apple watch such as accelerometers, gyroscopes, heart rate monitors, etc. In this research, we use the data collected every day by these sensors to collect data through the iPhone Health app and analyze the said data. In addition, we utilize these sensors to conduct a simple exercise evaluation examination, which can potentially help detect strokes.
