The Future of App Dev & PWAs


Progressive Web Apps (PWAs) - Should you care?!

To me, a PWA sounds like a type of glue. In some respects I guess that’s ok because we expect PWAs to be the glue that holds a bunch of mobile app companies together in the future. 

Put simply, Progressive Web Apps use web technology to deliver app-like experiences to users, right in their browsers.

PWAs allow for push notifications, they work offline and you can add them to your home screen. PWAs promise to be as good as, if not better, than native applications and they streamline the development process which allows you to develop apps faster and at a lower cost.

Progressive Web Apps are also truly cross-platform. That's because they are websites first that progressively become app-like. They can therefore, run on a smartphone, tablet, PC or Mac. Interestingly they are also installable just like regular apps. They do not have to be downloaded from Google Play or the Apple App Store. Users will not have to reach through a browser tab to access apps or websites. They just tap an icon and launch a mobile customer experience that looks and behaves like any other app. PWAs are generally designed to work from cached data when they are offline. This means that things like product catalogues can be viewed in offline mode as well.

PWAs consist of a few parts but the most important one is called a Service Worker. This acts independently of the web browser to provide the high performance and rich experience of native mobile apps, with the low storage space, real-time updates and improved search engine visibility of traditional web apps.

Some great examples of PWAs are:

  • AliExpress, a popular e-commerce site owned by the Alibaba Group. With a reported 104% increase in conversion rates for new users gained with their Progressive Web App compared to their traditional website and mobile app, PWA tech is driving the innovation behind Alibaba.

  • Flipkart is India’s largest e-commerce site. They recently updated their mobile site to a Progressive Web App called Flipkart Lite.

  • In 2017, Twitter rolled out its Progressive Web App “Twitter Lite” as the default mobile web experience for all users worldwide. With over 80% of users on mobile, Twitter wanted to improve its mobile web experience by making it faster and more engaging, especially because many of its users were located in areas with slow, flaky network conditions. Twitter Lite saw a 65% increase in pages per session, 75% in Tweets, and a 20% decrease in bounce rate. Twitter Lite loads in under 3 seconds for repeat visits even on slow networks.

So, look out as PWAs are the next big thing in mobile app development. This is the reason that Geronimo is already developing PWAs for brands like Optus and Blackmores.
