PaceJotter

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.

BUILT FOR EVERYDAY USE - Bold, readable numbers with light and dark appearances - Kilometres by default, with miles available in Settings - Whole-second or tenth-second display precision - Local storage for your saved paces and settings - No account, advertising, or internet connection required

PaceJotter calculates constant-pace times and splits. It does not predict equivalent race performances or adjust for hills, stops, or changing effort.
