Walking Speed Meter

Walking Speed Meter reads your Walking Speed and Step Count directly from Apple HealthKit and transforms them into medically relevant insights—instantly, privately, and on your iPhone. Multi-Scale Analysis — In addition to annual summaries, trends are calculated over 28-day and 56-day intervals to capture both seasonal and medium-term changes in mobility. Evidence-Based Design — Features are grounded in academic research on gait speed as a predictor of health outcomes, often referred to as the "sixth vital sign." Yearly Mobility Dashboard — A calendar-style grid visualizes average walking speed (m/s) and daily step count for each year, enabling easy comparisons. Trend Analysis — Track year-over-year changes, three-year moving averages, and linear regression slopes with R² values to understand long-term mobility trends. Variability Insights — Coefficients of variation highlight whether your walking speed remains consistent or shows instability over time. Plain‑Language Summary — Clear, human-readable summaries help you understand what the numbers mean and what actions might be helpful. On‑Device Processing — All computations are performed locally on your iPhone. Your health data never leaves your device. Zero Setup Required — Just grant HealthKit permissions once. New results appear automatically as fresh data arrives.
