2025
December 2025 — Sync across devices
Sign in to save your preferences and synchronize them across your devices. Signing in is optional — PHapp® stays free with no account required.
October 2025 — A redesign, built for accessibility
A brand-new design with a refreshed palette and improved legibility, meeting WCAG 2.1 Level A and AA. New Priority and Pinned sections surface urgent alerts and local resources, and you can now review expired alerts to see a community's recent activity.
June 2025 — NWS HeatRisk maps
PHapp® now includes the National Weather Service HeatRisk index — a forecast of heat-related risk over 24 hours, factoring how unusual the heat is, its duration, and CDC data on health impacts.
May 2025 — Trust & transparency
Map markers gained extended info and one-tap directions. Videos now carry Content Credentials (C2PA) — a verifiable "ingredient list" for how content was made. And anonymous view metrics show reach without any tracking or user profiling.
April 2025 — Maps, videos & local imagery
Custom maps show local resources for different alerts, native videos explain impacts and precautions, and agencies can distribute local flyers and community imagery in-app. Deep links now open directly in the app.
March 2025 — CDC charts + the web app
Updated Flu, RSV & COVID-19 charts from the CDC for each community, a refreshed design, and a new web version at ph.app.
January 2025 — PHapp® 3.0
The foundation for everything above.
