The major advantage of PWAs is that they do not require separate bundling or distribution. In particular,
there is no requirement for developers or users to install the web apps via digital distribution systems like Apple App Store, Google Play,
Microsoft Store or Samsung Galaxy Store. Most of the major app distribution platforms support PWAs, allowing them to be found in app stores.
Google Play, Microsoft Store, and Samsung Galaxy Store support PWAs, but Apple App Store does not. However,
the iPhone and iPad users still will be asked if they want to add the webapp icon to their home screens,
just like an app from the Apple store, bypassing the process of the Apple store download. Microsoft Store
publishes some qualifying PWAs automatically, even without app authors' request, after discovering them via Bing indexing.
