Sources and coverage
Apple Health exports fill the historical gaps; Intervals.icu remains preferred for movement where both have a value, and MacroFactor remains preferred for weight. Exported step totals are reconstructed with watch priority and phone fallback and may differ from the Health app. Historical weight uses daily scale medians; missing readings stay missing. Body-fat readings are scale estimates. Running totals exclude fragments shorter than 1 km or 5 minutes. Multiple recordings on one day count as one running day.
