In the last few years there has been exponential growth in the number of mobile phone users. Today, more than 60% of total internet usage is happening via mobile phone.
Obviously, the reasons include portability, cheap hardware, easy access to the internet and the increased number of services on the internet. With more users on mobile, the optimization of user experience on the phone is essential.
For smaller companies, which often do not have native apps due to cost or time constraints, the web app is the key opportunity where they can win customers by providing the best possible experience.
If companies have a dedicated native mobile apps, there is a possibility that many users will prefer their web version to avoid downloading and installing due to hardware and memory constraint or some other personal preference.
Meet progressive web applications
Let’s take the example of Whatsapp on your phone. When there is no network, you can still open the app, check past messages and even reply to someone. When the phone gets the internet connection, the messages are being automatically sent in the background.
This is what PWA promises to provide in web apps. It enables web apps to load when there is no network, sync in the background and seamlessly do things while providing a native-like experience for your users.
Why we need PWAs and what are their features?
Let’s discuss some of the core attributes which are missing from common non-progressive web applications.
The app should be lightning fast when loading, it should be close to instantaneous and should also open when there is no network or fairly low-speed network like 2G. Google found that 53% of the users abandon the website if the page took longer than 3 seconds to load.
