A quick guide to developing PWA apps for your business

by Sun Dew Solutions

Perhaps you're wondering what is Progressive Web App (PWA)?

There is a lot of buzz around PWA app with assertions that it is the future of web app development. Since its inception in 2015, it has taken the industry by storm because of the relative ease of development and excellent user experience which is equivalent to the native apps.

Progressive web applications are reliable, fast and engaging. It takes advantage of the most recent technologies to combine the best of web and mobile applications.  With such a combination, it is possible to create ultra-fast web pages that provide improved user experience, better visitor engagement, and increased conversion rates.

PWAs can be saved on desktops just like any native Android or iOS App.  These are specialized, Java-based websites that give mobile users an app-like experience. It loads fast and responds quickly all while using web technologies. PWAs bring significant benefits to businesses like higher conversion rates and customer retention.

So, let’s get into the core principles for better understanding: 

Connectivity or offline support

Poor internet connectivity won’t be the hindrance for launching PWA apps. They solve the slow connection issues and work on all possible scenarios. Regardless of bandwidth and latency, the navigation inside the app is fairly smooth.


High bounce rates are something that scares all business owners. The root cause of high bounce rates is slow page loading time.  As reported by Google, if a website takes more than 3 seconds to load, 53% of users abandon it and if the time exceeds to 5 seconds, the probability of the bounce increases by 90%.  So, this is where PWAs comes in making it readily available on the user’s device and browser.

Rail model

RAIL is mainly an abbreviation for describing key performance metrics. By analyzing human interactions with computer programs a user-centric model RAIL was created. This model can be applied to all user-oriented software programs like websites, desktop applications, mobile applications, and video games.


The essence of Progressive web applications is that it should have the feel and the capabilities of native apps and needs to be built on the application shell model, with minimal page refreshes. On the desktop, PWAs can be added to docks and taskbar. Also, shortcuts can be added to the desktop.


In a progressive web app, all network requests are intercepted through service workers so, it is imperative that the app is hosted over HTTPS to prevent man-in-the-middle attacks.

Merits of Progressive Web Apps (PWA)

Progressive Web App (PWA) offers a package deal of some lucrative features:

•    The size range of PWAs is way too light and can range in KBs which is much lesser than native apps.

•    Cost of acquisition is very low as it is easy to convince a user to visit a website than to install an app to get a first time experience.

•    Fewer efforts are required to build and release updates

PWA apps can build a strong mobile presence and drive your business in areas of poor internet connection. In the coming years, we are going to witness a massive rise in progressive app development. Mainly the areas like e-commerce, media, and restaurants can reap more profits and attract new customers with the implementation of PWA
