What Is a Web App (PWA)? Install Yapie on iPhone, Windows and Mac

- **Installs** from the browser with an icon on your home screen, dock or Start menu. - Opens in its **own window**, without browser toolbars. - **Loads fast and offline** thanks to a cached app shell. - Supports **notifications**, camera, microphone and file access (with permission). - **Updates itself** — no update button needed.
