Note: We're still working on this, so expect errors and bugs from changes we make. The calendar and safety monitoring features only work locally, and not on this deployed version, as the app hasn't been approved yet by relevant services. If you want to try out the calendar integration, email me at sopheo.contact@gmail.com and I can add you to the list of test users. The health data visualizations are based on an Apple Health data sample from Kaggle. Real-time monitoring and analysis of actual user data will be available in future versions.
