MoreBiAffect is a ResearchKit study app designed to understand the relationship between mood and neurocognitive functioning in bipolar disorder. It uses typing dynamics and passive sensor data from your iPhone to identify potential biomarkers.
The study welcomes both individuals diagnosed with bipolar disorder and healthy participants to serve as a control group. This helps researchers establish a baseline for comparison.
BiAffect collects data through keystroke dynamics, such as typing speed and errors, and passive sensor information from your iPhone's accelerometer. This data is used to analyze 'virtual mental-health footprints'.
Currently, BiAffect is supported on iPhone and iPod devices. It is not available for Android smartphones at this time.
The app aims to provide objective psycho-physiological markers by analyzing typing patterns and sensor data. While not a replacement for clinical diagnosis, it seeks to offer more objective insights than traditional self-reports.
The latest version of BiAffect is 2.2.0, which was last updated on August 16, 2020. This indicates a moderate update frequency for the application.
BiAffect has an age rating of 12+, making it suitable for teenagers and adults interested in participating in health research.
No, BiAffect does not contain advertisements. As a research study app, it focuses on data collection for scientific purposes without commercial interruptions.
