Nowadays, a simple app downloaded from the App Store or Play Market is unlikely to please you. The sheer number of applications available on various platforms is mind-boggling. The number of competitors is also increasing. As a result, developers have less opportunities to grab clients' attention and persuade them to download yet another standard app. Progressive Web Apps are abbreviated as PWA. Google was the first to coin the word in 2015. It's best described as "as the user forms a relationship with the app over time, it becomes more and more strong." PWA Websites are still websites. Thanks to new web technologies, they just look and sound like an app. Users will access Progressive Web Apps with a URL in their browser, much as they will any other website, but immediately after landing on the PWA, they would have the experience of using a "app" right in their browser, without the need to download and install something. In short Progressive Web App (PWA) is a website that looks like an app that can be activated on a smartphone, mobile, notebook, or desktop computer. PWAs will submit push updates, much like normal apps. A symbol for such an app appears on your home screen after it has been downloaded. Progressive web apps (PWAs), as you can see, merge the features of web and smartphone apps. PWAs are unique in that they can be used on any website as long as it has a standards-compliant browser. It's a creative, effective, and easy way to translate web data to a mobile app such that consumers have a better and more complete experience. Moreover, progressive web app developers optimize web applications, providing app-like navigation and excellent visual content. Most of the features that were formerly only included in native apps are now included in PWAs. This includes camera and microphone control, GPS, offline mode, file access, and many other device-level features. Regardless of the network link, they provide secure and instant loading. As a result, it improves navigation and speeds up loading times. PWAs are fantastic replacements to smartphone apps. They are much less expensive to produce and are cross-platform by nature, eliminating the need to create different Android and iOS versions. Users do not need to go to the app store with PWA. Progressive mobile services, unlike native software, do not necessitate time-consuming activities such as installing. The Pinterest PWA, for example, is just 150 KB in size, compared to the 9.6 MB and 56 MB needed to provide this experience on Android and iOS, respectively. Businesses fail to develop an innovative technical approach to have a personalized service for their customers. At the same time, the latter have a hard time finding an app that is really worth their time. As a result, conventional smartphone app creation is becoming more expensive and time-consuming, while user interface is becoming increasingly sluggish and tangled. As of right now PWA helped many company not only increase conversion by 60% but also decrease the bounce rate by 50%. So this is why most of the companies are migrating towards this new technology. Looking at the rate there is nothing that can stop this to get on top in coming Years.
