About CalcuSplit
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!

What’s new
Version 2.5 · Updated October 12, 2026
CalcuSplit 2.5 is rebuilt for iOS 26 and Liquid Glass. A fuller screen. Each runner takes about a quarter less room, so you see roughly twice as many at once — six where you used to get three. Their name now sits on the same line as their times. A clock you can read across the track. Bigger, and pinned above the list so it stays put while you scroll. Harder to mis-tap. Finish is smaller and set apart from Lap. If you do hit it by accident, an Undo appears for a few seconds. Reset only shows up while the clock is paused, and asks before clearing anything. On iPad, runners fill the width in two or three columns — a whole heat with no scrolling. Relay results read leg by leg, with each runner's leg time and splits under their name. Texting results moved to a single button at the top of the results screen. Also: sort your roster by first name, last name or gender; swipe or hold to delete an event or runner, with a confirmation first; Smart Sort moved to the top bar so it can't scroll away mid-race. Requires iOS 18 or later.
