The story of how you move. Steps and distance first, every activity counted, and your whole history at a glance.

Preview of the next update
The upcoming Station look puts today’s steps in a large central count on a circular HUD, with distance on a digital display. Coloured bar segments distinguish activities within the same day, from a week to your lifetime archive. Classic photographic looks remain available as a choice.

  • Steps and distance in kilometres and miles, today’s steps right on the app icon, plus Home Screen, Lock Screen and StandBy widgets.
  • Every activity counts - walking, running, cycling, swimming, skating, rowing and more, from Apple Health.
  • A meadow that blooms as your day fills up, and a goal that follows your own last 30 days. No streaks, no guilt.
