A Progressive Web App (PWA) is a web app that uses modern web capabilities to deliver an app-like experience to users. ... You can deploy your app as a PWA as well as Native app and take advantage of both channels. Ionic allows you to ship your app to not only the app store, but also deploy to the mobile web as a PWA.Progressive Web Apps are user experiences that have the reach of the web, and are: Reliable - Load instantly and never show the downasaur, even in uncertain network conditions.Fast - Respond quickly to user interactions with silky smooth animations and no janky scrolling.Engaging - Feel like a natural app on the device, with an immersive user experience.This new level of quality allows Progressive Web Apps to earn a place on the user's home screen.

Native app store apps do things like send push notifications, work offline, look and feel like an app (as Apple and Google have imagined them), load on the homescreen, and so on and so forth. Mobile Web Apps accessed in a mobile browser, by comparison, historically haven’t done those things. Progressive Web Apps fix that with new Web APIs, new design concepts, and new buzzwords.
