Set a goal. Watch it fill up. Pebbles turns any sports goal into a pebble you fill. 1,000 km of running in a year. 10,000 steps a day. 12 workouts a month. 500 km up to race day. Apple Health fills your pebble on its own, and the widget on your Home Screen shows where you stand. THE PACE LINE A dashed line shows where you should be today. Above it, you're ahead. Under it, Pebbles calmly shows where you're heading. No red, no streaks, no guilt. ANY GOAL, ANY LENGTH • A year, a month, or your own dates, like a marathon block or a summer • Running, walking + running distance, steps a day, workouts, cycling, swimming, hiking and exercise minutes, straight from Apple Health • Goals that start again every year or every month • Count anything else with +1: books, trips, concerts THE WIDGET IS THE APP • Home Screen widgets with one, two or four pebbles • Lock Screen widgets • StandBy Glance at your phone, see the number, get on with your day. NUMBERS THAT HELP • What fills it from here: "16.5 km a week fills it" • This week, every month, your best day and your longest run • A forecast whenever you're under the line • Compare with last time • A look back when a pebble ends, to save and share PRIVATE BY DESIGN Pebbles only reads Apple Health and never writes to it. No account, no server. Nothing you track leaves your iPhone. TWO LITTLE NOTES A Sunday check-in and a note when a pebble fills. That's all. FREE AND PRO Free: one Apple Health pebble of any length, the small widget and the Lock Screen widgets. Pebbles Pro is a single payment, no subscription: unlimited pebbles, counters, repeating pebbles, every widget size and style, compare with last time, and look-back cards to share.

Performance Logging Race data is automatically saved to each athlete’s profile, improving prediction accuracy over time and giving coaches deep insights into performance trends.
