The Rise of Progressive Web Apps (PWAs): Offering a Native App Experience on the Web

As of May 2024, a staggering 62.15% of the global market share for web browsing now belongs to smartphones and tablets [Source: Statcounter]. This shift in user behavior has led to the rise of mobile apps, offering a convenient and personalized way to interact with everything from social media to banking.

However, even with app stores overflowing with options, users face challenges. Discovering the perfect app can be cumbersome with countless options vying for limited screen space and attention. Furthermore, app size can be a major obstacle. Downloading hefty apps can consume a lot of storage space, especially on older devices. Moreover, dependence on app stores creates a barrier to entry, leaving valuable functionalities undiscovered by users who simply don’t come across the right app.

Progressive Web Apps (PWAs) offer a plausible solution to these challenges. PWAs bridge the gap between the convenience and functionality of native apps and the accessibility and discoverability of the web. They offer an app-like experience directly through your web browser, eliminating the need for app store downloads and hefty storage requirements.

What are Progressive Web Apps (PWAs)?

Progressive Web Apps (PWAs) are web applications that provide a native app-like experience to users. They combine the best of both worlds, offering an app-like experience accessible directly through your web browser. But what exactly makes them "progressive"?

Web development companies build PWAs on the principle of progressive enhancement. This means they start as basic web pages that work flawlessly on any browser, and then progressively add features and functionalities based on the capabilities of the device and browser being used. This results in a smooth experience for everyone, regardless of their device or internet connection.

At the core of a PWA are several key functionalities that facilitate its native app-like capabilities.

• Service Workers

These act as invisible behind-the-scenes helpers, offering features like offline functionality and push notifications. Service workers essentially pre-cache essential app content, allowing users to interact with the PWA even without an internet connection. Additionally, they act as a communication channel, facilitating push notifications to keep users updated on relevant information.

• Web App Manifest

This acts as a blueprint for your PWA, providing essential information like app name, icons, and splash screens. Essentially, the web app manifest is a JSON file that contains metadata about the PWA, such as its name, icons, and splash screens. The Web App Manifest also plays a crucial role in allowing users to install the PWA on their home screen, creating a native app-like experience.

By leveraging the web, PWAs can reach users across multiple platforms and devices, increasing their potential user base.
• Reduced Development Costs: PWA web app development can be considerably cheaper than creating a native app, as it requires only a single codebase for all platforms. This reduces the costs of web app development, testing, and maintaining multiple apps for different platforms. Furthermore, PWAs can be easily updated and maintained, reducing the costs associated with app updates and maintenance.
• Easier Maintenance: PWAs have a single codebase, making maintenance and updates easier and more efficient. This reduces the complexity and costs associated with maintaining multiple apps for different platforms. By having a single codebase, developers can easily update and maintain their PWA so that users always have access to the latest features and updates.
• Improved SEO: Content remains discoverable by search engines, which improves the PWA’s visibility and search engine ranking. This is especially beneficial for developers who want to increase their online visibility and drive more organic traffic to their PWA. By optimizing their PWA for search engines, developers can increase their visibility and drive conversions.

Use Cases for PWAs

PWAs aren't confined to a singular niche. Their versatility extends across various industries, offering unique advantages to both users and businesses.
