Trialist — Health Experiments

Trialist is a health app that tests personal experiments by comparing Apple Health data to determine the effectiveness of interventions like supplements or workout timings. It auto-syncs with Apple Health to track over 20 metrics, providing statistical confidence scores and A/B experiment comparisons without manual data entry. Users can log interventions, and Trialist analyzes the data to show real percentage changes, such as improved sleep on days when magnesium is taken. The app offers features like dosage tracking, PDF reports, and a calendar view to identify patterns, ensuring 100% privacy by keeping data local.
