What is Progressive Web App?

Progressive Web Apps also are known as PWAs are the web apps that look and feel just like a native mobile app. It works on any browser whether it be chrome, opera or Samsung internet browser and the users are not obliged to download from the app store. Just tap on the link and PWA is installed on the user’s phone.

Just like a native mobile app, a PWA is displayed on the homepage, in the app drawer, sends push notifications and integrate into system settings.

The Idea of Progressive Web Apps

Google compared top 1000 mobile apps vs. top 1000 mobile app properties (web) to study the reach and user engagement. The results of the comparison showed a great disparity in user behavior.

According to the study, mobile web reach is way higher than native app reach. It was 11.4 million unique visitors per month compared to 4 million visitors.

Whereas the stats of user engagement with services showed that users tend to spend more time on native mobile apps compared to the mobile web. It was an average of 188.6 minutes on app against 9.3 minutes on the web.

So, the idea was clear. They wanted to provide a native app like engaging experience to users on the mobile web. In this way, Progressive Web Apps were developed to deliver amazing user experience on the web.

Benefits of PWAs

Reliable Despite of Network Flaws

One can rely on Progressive Web Apps even when the network is shoddy as it can even work offline. This is possible through service worker, a type of web worker. Konga, a leading e-commerce website in Nigeria managed to reduce 92% of the user data usage due to its Progressive Web App.

Looks and Feels Just Like a Native App

The user won’t notice any difference between PWA and the native app. It exactly looks and feels like a native app and even provides similar features like push notification, integration with the system, display icon on the home screen and app drawer, etc.


Making the user install your app from the store can be a pain in the neck. But with a PWA the user can install the app with just one tap. This frictionless installation lets users enjoy service instead of installing the bulky native app.

Easy Updates

One of the most amazing features of PWA is that it is easy to update. Since there is no app store that works as a mediator, your users can enjoy the updated app as soon as you have updated it from your side.


Even though PWAs are packed with amazing features, they are extremely lightweight. Comparing Pinterest’s PWA with its Android and iOS app, it is just 150KB against 9.6MB and 56MB respectively. Charmingly lightweight, isn’t it?
