CLUSTER MOBILE-OFFLINE-EMERGENCY · 23 ENTRIES · EARLIEST ENTRY 2025-08-21
Offline emergency preparedness apps
The cluster is composed of offline-first apps providing emergency information, maps, communication, and preparedness tools for consumers, responders, and humanitarian aid workers. Dated entries before the index start are sparse, with single launches in isolated months spread across 2010 through 2026, indicating a long but thin history rather than a concentrated pattern. The strongest traction signal is sandya with 3 stars, followed by RescueMate with 1 star, while ember-vault shows no traction yet.
Entry timeline
ENTRY TIMELINE
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 3 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
