Progressive Web Apps (PWA): Definition, Key Benefits, and Use Cases

Trends come and go so frequently in the tech world that it’s hard to foresee the next big thing in technology. However, one thing that is definitely here to stay is the progressive web app phenomena.

You may not have heard of them yet, but progressive web apps (PWAs) have already started making waves. So what are progressive web apps exactly?


What is a PWA?

Wikipedia explains that a progressive web app is a web application that loads like a regular websites but can offer the user functionalities such as working offline, push notifications, and device hardware access traditionally available only to native applications. PWAs combine the flexibility of the web with the experience of a native application along with other best practices.

They strive to deliver an unsurpassed experience for mobile users. PWAs are reliable and respond more quickly to users. Additionally, they focus on engaging mobile users with a more immersive experience than ever before.


According to Google, a progressive web app should offer the following three things:

  • Engagement: Apart from engaging content, a progressive web app should allow you to add the app to their home screens. It should also be able to send push notifications to users.
  • Speed: Speed is an important aspect of progressive web apps. They should load instantly not taking more than three seconds.
  • Reliability: A progressive web app should be designed to work offline and in areas of low connectivity.


What are the benefits of PWAs?

PWAs are known to offer many benefits to businesses. Let’s take a look at them:


  • Low data usage: PWAs don’t need too much data to run as compared to native apps. For instance, if a react native app consumes 10-15 MB data, a progressive web app will just need 500 KB or so. Also, they don’t need any significant storage on the device either.
  • No updates required: PWAs are similar to websites which means they are updated as being used by the user. Unlike native apps, these aren’t updated in the background. The best part is that they can be updated much quicker as no Play or App Store approval is required.
  • Low costs: Developing a native app for Android and  iOS phones is a costly affair for businesses especially for startups. Thus PWAs come across as a wise option for businesses as they reduce the cost of development by 60-70%.
  • Faster speed: Speed is an essential aspect of progressive web apps making them load almost instantaneously. You can browse, shop, view things in lesser time as it would take on web browsers. Faster speed could lead to higher conversion rates means PWAs make attracting customers easier than ever.
  • Offline capabilities: Progressive web apps changed  the game when they allowed apps to run offline. Offline capabilities allow users to access the app even in low reception areas at faster speed leading to more user engagement and higher conversion rates.
