STOPer

STOPer is a precision sports timing app built for coaches, PE teachers, and athletes.

STOPWATCH

Clean, distraction-free stopwatch with lap splits. Every session is automatically saved with date, duration, and all split times. Export any session as CSV for analysis in Excel or Numbers.

GROUP TIMING

Time multiple athletes simultaneously. Add names before the session or on the fly. Stop each athlete individually — STOPer records their time the moment you tap. View results ranked by time, export the full session as CSV.
