A PWA (Progressive Web App) is a cross between application and mobile website. It is a hybrid internet revolution that uses new web technologies to deliver application like experience to users.
Technically speaking, PWAs are your regular web pages but they appear like an application to its users. This innovative idea uses best of both worlds of native application development and hybrid app development language for web apps to create an interactively enhanced experience for users.

PWA enables cross-support to users that allows switching between devices by providing continuous experience. Here, the users can access the app using the same setting and data on another device. Along with that PWA can adapt to various screen sizes no matter what the app version is.
The next advantage of PWA is to implement push notifications on mobile devices. The developers have full access to control and enforce this feature with regards to advertising new content and promotions.
PWA will help in improving the conversions for new users as it’s a kind of reliable option where the technology allows users to send push notification even after the application has been closed. These apps will update itself every time when the users visit it, thus eliminating the need to download batch changes and installing it.
