PaceJotter
Pace calculator & race splits
Free · Designed for iPad. Not verified for macOS.
Your next PB starts with a plan. Calculate running paces, save your benchmarks, and turn race goals into clear kilometre, mile, or track splits.
Find your pace. Plan your splits. Keep the numbers that matter.
PaceJotter is a running pace calculator for iPhone and iPad. Turn a target time into a pace, work out your finish time from a pace, and save your personal bests, race goals, and everyday training benchmarks.
CALCULATE IN EITHER DIRECTION
Choose a distance and enter either your pace or your target finish time. PaceJotter calculates the other instantly. Switch between kilometres and miles whenever you need to.
FROM THE TRACK TO THE MARATHON
Pick common distances from 100 metres to 100 miles, including 400 metres, 1K, one mile, 3K, 5K, 10K, half marathon, marathon, 50K, and 100K. Enter a custom distance in metres, kilometres, or miles.
YOUR PACES, READY TO REUSE
Save named personal bests, race goals, and training paces with dates and notes. Search your collection, filter by category, and load any saved pace into the calculator.
SEE YOUR SPLITS AT A GLANCE
What is a 400-metre lap at your 5K pace? Open a saved benchmark and see 200-metre, 400-metre, kilometre, and mile times immediately. Add another distance for a quick comparison.
MAKE A RACE PLAN
Set a race distance and finish-time goal, then view kilometre, mile, track-lap, or custom splits. See each interval time alongside cumulative elapsed time, including the final partial interval. Share your plan with the iOS share sheet.
