Personal Best for iPhone Duo

Adapted for the fold

• Closed · Outer display

  Replays and Today, closed

  Shut, a workout replay stacks the route map, heart rate, distance, calories and the scrubber on the cover, and the tabs move into a rail down the right edge.

• Open · Inner display

  Map beside the stats

  Open flat, a replay's map fills the left with heart rate, distance, calories and the scrubber beside it. Workouts sit beside your yearly and monthly totals, a workout's splits and map beside its summary, and a month's calendar beside its recap.

• Book · Partly folded

  Laptop-style replays

  Half-folded like a laptop, the map and stats stay on the upper half while play, skip, map style and replay speed move to the lower half above a scrubber.
