SplitStack: Team Stopwatch

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.

Main features:

• Multiple independent stopwatches
• Multiple teams with horizontal paging
• Add, rename, reorder, and delete members
• Individual and team-wide start/pause controls
• Lap and session history
• CSV export through the iOS share sheet
• Three appearance themes

Core timing data is stored on your device. You choose where it goes when you export or share a CSV.

SplitStack keeps every person's time in view.
