PHapp® is co-developed by the Wehealth® community — public health departments, emergency managers, researchers, and partners who help shape every release.

That is why it works in the real world. Agencies can review PHapp for their community, promote it to residents with free multilingual materials, and access core agency tools without a contract or setup fee. Optional paid services are available later for teams that want more customization, analytics, or implementation support.
