Progressive Web Apps (PWAs) are a significant step towards this innovation. Put in simple words, progressive web apps are websites with the look and feel of a mobile app.

A Growing Marketplace for PWA

The primary focus elements for every business are the retention of existing customer base and reaching out to the potential customers. Higher conversion rates ensure that the revenue generation stream remains stable in the future.

Apart from this, among other recent developments, Google recently announced that page speed will be considered as a search ranking parameter. With this progress, it can be expected that the inclination towards the adoption of PWAs will rise at a steady pace.

Market Overview – Progressive Web Apps

The global corporate arena has been positive responsive towards PWA adoption at a significant scale. There are quite a few international brands that have launched their very own PWA.

Progressive Web Apps are new age web applications which are characterized by regular loadings like that of any website or web page but with certain additional functionalities. They can work offline and push notifications along with device hardware access. The last one is primarily available only to native applications. Hence, progressive web apps are a combination of the best of both platforms. It offers the flexibility of a web with an enhanced experience of native applications. As a result, it is the advanced mechanism of customer experience. The users get a mobile app like feel through the browsers.

Progressive Web App Benefits

After an insight into what is a progressive web app, it is essential to understand the utility of the same. Progressive web app benefits are both technical and business-centric in nature.

All these are accessible from the Chrome menu and the Start Menu. They can also be used as pinned apps on the taskbar. Subsequently, they are also available in the Microsoft Store.

Progressive Web Apps on iOS

PWA apps are receiving a lot of attention in recent times. Hence it has become essential for the different platforms to incorporate PWA functionalities. iOS is no different. With the launch of iOS 11.3, the support for PWA is already visible. Therefore, now the users can install applications without the approval from the iOS App Store.

There are certain features related to this development. The users have access to certain functionalities with the web platform on iOS. These include geolocation, sensors, camera, audio output, and Apple Pay to name a few. However, users will not be prompted or there will be no invitation for the PWA apps. The users need to visit a specific PWA URL in Safari and press the share icon followed by the “Add to Home Screen” option. Hence there is no specific indication that the visiting website is a PWA. This is one of the setbacks currently for progressive web apps on iOS.

Progressive Web App Framework

It is important to choose the appropriate progressive web app framework in order to optimize performance and business benefits. Below are some of the popular choices of frameworks for PWA.

Angular PWA

Ionic includes Cordova Plugins and robust CLI for cross-platform application development. Additionally, there are rich UI elements that are advantageous for Ionic PWA development.


Progressive web apps are a significant step forward into application development segment. Mobile application and websites both contribute significantly towards enhancing customer experience. PWA apps are a stride ahead in this approach. They combine the best of both the mobile application and website features. It is important to understand that every business has its very own app. However, downloading and installing apps for every product, service or platform is not a feasible solution. PWAs are a fresh outlook to the scenario. Without installation, progressive web apps provide the benefits of website browsing through the look and feel of the application. Thus, it can be predicted that they are the future in the app development sector.
