Tempo Pace Calculator

Tempo turns your running pace into something you can see and feel.

Set a pace on the ruler and the whole screen takes its temperature: cool teal when you are running easy, red hot when you are flat out. The background is a living gradient that shifts with every second you scrub.

PACE, INSTANTLY
Drag the precision ruler to any pace and read it like a scoreboard. Every tick gives a light haptic tap, so the value has real texture under your thumb.

FINISH TIMES FOR EVERY DISTANCE
See your projected time across 400 m, the mile, 5K, 10K, half marathon, marathon, and the ultra distances. Pin your favorites to a grid on the home screen.

CADENCE METRONOME
Lock in your step rate with a metronome that taps the beat onto your wrist with real haptics, not just a click. Link it to your pace or run it on its own.

SIX ICONS, ONE SHADER
Choose the app icon that matches your mood, from ice to fire. Every icon is rendered from the same live gradient that paints the app.
