Web apps that use service workers, manifests, and other web-platform features in combination with progressive enhancement to give users an experience on par with native apps.
Progressive web apps are a collection of features that, starting today, will make it easier to build, run and scale your app faster. We’re going to allow developers to embed a web-based version of their app on any device with a browser and access it right in the app store. This will give users access to all the same functionality of their full desktop experience without having to download an entire app onto their phone or tablet. That means you can start using your app as soon as you’ve uploaded it with no additional hoops to jump through.
