CLUSTER CRUISE-ACTIVITIES-BOOK · 5 ENTRIES · EARLIEST ENTRY 2013-09-06

Cruise companion apps

This cluster consists of mobile companion apps for cruise passengers, covering trip planning, check-in, activity and excursion booking, onboard experience management, dining reservations, and onboard chat. The cluster's dated history is too thin to read a shape from—only three dated entries predate the index start, so no trend can be inferred. Traction leaders, based on the highest activity signal, include Holland America Line Navigator, Carnival HUB, and Disney Cruise Line Navigator, each with 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 5 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
