As the technology knows no boundary and can swing any direction (downwards or upwards) anytime, PWA now getting high attention by the business organisation to reach its target audiences.

What is Progressive Web Apps?

Before we dive deep any further, let’s understand what PWA (Progressive Web Apps) is and how it is going to be the future of mobile apps (at some extent).

In simple term, Progressive Web Application is not an actual app but using modern web capabilities, it offers app-like experience to users.

You may have come across “Add to Home Screen” pop-up when you open a website (modern web capabilities feature that is available now with all modern browsers) in the browser.

When you allow it, you get a “Lite” version of the app created on your desktop or mobile which offers native-app like experience.

Besides, you get offline functionality as well. But, there are some different views on the offline features of the PWA apps. For example, not all PWAs function offline; one such example is ‘Instagram.’

Instagram PWA

When you add Instagram as PWA, you can use it when you are online, but it does not function when you are offline. However, the Native App function offline (but only 4 to 5 feeds are visible) too.

Why PWA?

PWAs are helpful to solve number of issues like internet speed, slow website load, and user engagement and provide better support to both users and service providers. For example, as we have already mentioned that there are businesses who do not have native apps can get the maximum advantages of PWA by targeting a large number of audiences who are mostly mobile users.

Besides, the user who does not want to install native apps due to the less storage capacity and RAM can also get benefit of it.

Benefits of Progressive Web Apps

In coming days or even years, PWA will replace the native app. Isn’t it shocking a unbelievable this speculation has been made by the global research and advisory firm, Gartner.

Besides, the number of apps in mobile phone impacts on its ram and hard drive and therefore, most of the users restrain from downloading native apps.


The Gartner Report also projects that by 2020, 50% of “general-purpose, consumer-facing” native mobile apps will be replaced by PWA.
