Description by University of Illinois Written by the developer, not by AppBrain. Click to read.
BiAffect3 is the new and improved version of our award-winning BiAffect app, part of a multi-year mood-tracking research project developed by researchers at the University of Illinois at Chicago and funded by the National Institute of Mental Health.

BiAffect3
• Track your mood and neurocognitive functioning with your iPhone.
• Use keystroke dynamics and sensor data to gain insights into your mental health.
• Help researchers develop new tools to improve the diagnosis and treatment of mood disorders.

How does it work?
BiAffect3 uses a custom-built virtual smartphone keyboard to collect keystroke metadata—such as typing speed, errors, and pauses—but not typed content in order to preserve user privacy. This data is then analyzed using machine learning algorithms and other statistical techniques to identify patterns that are associated with different mood states.

Who is BiAffect3 for?
BiAffect3 is for anyone who is interested in tracking their mood and neurocognitive functioning. The app is particularly useful for people with mood disorders as it can help them to identify early warning signs of an episode and take steps to prevent it, but it can be used by anyone who wants to learn more about their individual emotional and thought patterns.

How do I get started?
To get started with BiAffect3, simply download the app and create an account. The app will then guide you through the setup process.

How can I help?
By participating in the BiAffect3 study, you can help researchers develop new tools to improve the diagnosis and treatment of bipolar disorder. Your participation is voluntary and confidential.

Download BiAffect3 today and start tracking your mood and neurocognitive functioning.
