About this app
CalcuSplit is designed to be a runner's best tool at the track. Whether you are a high school coach, friends holding an informal 5K, or just trying to help your running buddies reach their next PR, CalcuSplit makes it easy to time laps for multiple runners. One coach, one device, a whole heat. Every runner gets their own row with their own Lap and Finish buttons, so nothing gets written on a clipboard and nothing gets reconstructed afterwards. --- It couldn't be easier! - Add and track multiple runners - Time races, relays, and interval workouts - Hand off between legs in a relay and see each leg's time on its own line - Select participants for an event and start tracking - Get your results, including lap and finish times - Text each runner their own result when the race is done - The screen stays on while timing, so you don't have to worry about the device locking during a race - On iPad, runners fill the width in two or three columns, so a full heat fits without scrolling CalcuSplit Premium unlocks - View each runner's race/lap history and track their progress across the season - View past events and export the results as PDF, HTML, or CSV for easy sharing - Bulk import runners from a spreadsheet or CSV file --- All data is securely stored on your iPhone. No ads, tracking, or external servers. That also means that CalcuSplit will work anywhere, even in areas with no cell service! If your systems administrator has any questions, please have them contact me at CalcuApps@iannaz.zone.
What's new
Version 2.6 · Oct 30, 2026
CalcuSplit 2.6 is made for iPhone Duo and iPad. • iPhone Duo: closed, it’s the CalcuSplit you know. Open, it gets the iPad layout, and folding or unfolding mid-race never stops the clock. • iPad: a sidebar replaces the tab bar, and Runners and Event History show the list beside the runner or event you open. • Resize the app mid-race with Split View, Slide Over or Stage Manager, and timing carries on. • With larger text, the timer uses fewer, wider columns so names stay readable.
