One arrival, held from a pill to a full screen.

The arrival follows the rider across the Dynamic Island, the Lock Screen, and StandBy, so one activity has to hold from a compact pill to a full screen. The track, the position on it, and the time never drop, and the route's gradient carries line identity at every size.

Apple requires a single Live Activity to support four presentations, and the compact one is split in two by the TrueDepth camera — a leading element and a trailing element that must still read as one piece of information.

At 52 points wide there is room for a track, a position on it, and a time. Everything else was cut rather than abbreviated, because a value that only survives in the expanded presentation is a value the rider learns not to look for.

Apple does not allow a custom background in the compact, minimal, or expanded presentations — they render on black. Identity had to come from the content itself, so the route gradient became the one element that survives every size.
