$1.99
iPhone
Run a separate stopwatch for every athlete, switch between teams, keep a clean session history, and export results to CSV for your spreadsheet.
SplitStack is a multi-person stopwatch built for coaches, club managers, trainers, and teams that need to time several people from one iPhone.
Use it for track and field, swimming, cycling, motorsport, school clubs, group training, client sessions, and any activity where every person needs an independent clock.
TIME SEVERAL PEOPLE AT ONCE
Create a separate stopwatch for each member. Start, pause, resume, record a lap, or finish each timer independently. You can also start or pause everyone in the current team together.
SWIPE BETWEEN TEAMS
Keep different squads, events, classes, or client groups in separate team workspaces. Swipe horizontally to move to the people you need without rebuilding your list.
KEEP A CLEAN HISTORY
Finished sessions are saved on device with their team, member, start time, end time, elapsed time, and laps. Results stay connected to the person who recorded them.
EXPORT TO CSV
Export saved history as two spreadsheet-friendly CSV files: a session summary and a row-by-row lap detail file. Share both through AirDrop, Mail, Files, or another iOS share destination, then open them in Excel or your preferred spreadsheet app.
CHOOSE YOUR LOOK
Switch between Plain, Sports, and Luxury themes. Every theme keeps the same familiar controls.
