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.

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.
