Simple Pace: Run Calculator

On a relay team? ETA counts down to your teammate reaching the exchange, on the Lock Screen too, and saves the pace each leg was really run. Pro is a one-time purchase.

Distance, time, pace and speed, always in sync. Change any one and the others follow. A lock holds the value you care about while you work out the rest.

On a relay team, or waiting for a runner at a race? ETA tells you the clock time they reach you, with a live countdown that carries on to the Lock Screen and up to three alerts. Tap when they arrive and the leg is saved with the pace they really ran.

FREE • Four linked calculators: tap any value to edit it, tap a unit to switch between miles and kilometers. Every row keeps its own units. • Race distances built in: 400 m, 5k, 10k, half-marathon, marathon, and ultras from 50k to 100 miles. • Share card: send your distance, time and pace as an image. • Make it yours: light or dark, eight accent colors with matching app icons or the Multicolor theme that gives distance, time, pace, and speed each their own color, reorderable sections, and the Classic interface if you prefer it. • Accessibility: VoiceOver, Voice Control, Dynamic Type, Sufficient Contrast and Reduced Motion. • All calculations work offline. Seven languages.

PRO (one-time purchase, no subscription) • Splits: plan even, negative or positive splits at any interval from 100 m to 10 miles, by halves, thirds, quarters or fifths, or an interval of your own, then export the table. • ETA: made for relay exchanges and race spectators. Each runner gets a card with the arrival clock time, a live countdown, estimated progress, up to three alerts and a note. The countdown also runs on the Lock Screen, in the Dynamic Island and as a badge on the main screen. Tap They are here to save the leg with the pace actually run; finished legs stay in a list you can edit and share.
