PWA or Progressive Web Application is a term used to describe web apps that use modern web technologies to provide an app-like experience to users. Synonyms for PWA include Hybrid Apps, Web Apps, Responsive Apps, and Offline First Apps. Hybrid apps combine the best of both worlds, that is, the web and native apps. Web apps are similar to traditional websites but have added functionality that allows them to function like an app, such as push notifications and offline access. Responsive apps are designed to adapt to different screen sizes and offer a consistent user experience across devices. Offline first apps are designed to work without internet access and ensure that the app's functionalities remain intact even when offline.
