What is Trialist — Health Experiments?
Most health apps track habits. Trialist proves if they work. Test personal experiments: Does magnesium improve sleep? Morning or evening workouts better? Log interventions and Trialist auto-compares Apple Health data (sleep, HRV, 20+ metrics) on intervention vs baseline days with real stats. Unique: Auto-syncs Apple Health, statistical confidence scores, A/B experiments, dosage tracking, PDF reports, 100% private (local-only). Turn self-experimentation into science.
