How PHapp Works.
See how PHapp delivers official alerts by app, web, and text — and how community input, human review, and public-benefit values shape the experience.
During the heat wave, PHapp sent me an alert in Spanish before I saw it on the news. I could check on my parents and help keep them safe.

I signed up after a flood warning. Now I get all my local alerts in one place. I do not have to check five different apps and websites.
