Every run, walk, hike and ride you've done, drawn on paper. Scribble Run reads your workouts from Apple Health and draws each route in ink on a plain notebook page. That's it. – Tap a drawing to look closer: distance, pace, time. – "So far" puts every route on top of each other. Pick a year, or put them on a map. – Choose how many drawings fit on a row. – Write with ink, pencil or biro. – Widgets: your last run, so far, a logbook, this week. – Opens like a book on iPhone Duo. No account. No ads. Scribble Run only reads from Health. It never writes. Everything is free and nothing is locked. If it makes you smile, pay what you want.
