Calculator For Runner (CalcForRun)

CalcForRun is a runner-focused calculator that makes it simple to compute pace, lap times, and distance-based speed. Enter distance and elapsed time to derive pace, or enter pace and distance to find elapsed time. The interface mirrors a standard calculator for familiarity, with a dedicated pace screen for quick splits.

Version 2.2 adds Track mode to display split times by track distances (800m, 1km, 1.5km, 2km, 5km, 10km) and a cheering-point crossing estimator. Version 2.0 introduced small-display compatibility, one-touch distance presets, and flexible time input (seconds, minutes, hours). The app enforces clear time rules and supports time-based calculations for speed and distance.
