Walk a measured distance at your normal, comfortable pace and let the app time it. It converts to gait speed in metres per second — one of the most studied functional signals in adults. This tracks everyday mobility, not survival or health status.
Measure a straight path. A 4-metre or 6-metre course is standard. Give yourself a step or two before and after so you're already walking at the start line.
Tap start as you cross the start line, tap stop as you cross the end line. Or enter a time you measured with a stopwatch.
