The Current State of Progressive Web Apps

The Current State of Progressive Web Apps

By 2020, Progressive Web Apps will replace 50% of all consumer-facing native apps, according to Gartner Research.

A progressive web application (PWA) is mobile web page that acts and feels like regular native app. Like all apps, PWA can be accessed via the home screen of any smartphone. PWAs also share many of the same functionalities of native apps and provide a nearly identical user experience.

PWAs can be described as being:

  • Reliable: Load instantly even when offline or connected to slow network
  • Fast: Respond quickly to user interactions with clean animations and smooth scrolling
  • Engaging: Feel like a native app with an rich user experience

Advantages of PWAs

Progressive web apps bring a number of advantages to the table. For example, PWAs compared to native apps are much smaller files making them less of a burden on a device’s storage.

Connectivity

PWAs use less data and can operate on slower networks (3G or less) or when offline thanks to service workers.

Updates

Updating a PWA is also significantly easier. In fact, as a web page, PWAs are updated automatically when the site is updated freeing users from having to manually update their PWA. This also ensures all users are have the latest version of the PWA.

Cost Efficient

PWAs are quite cost-efficient. While apps need to be specifically developed and maintained for different operating systems, the same PWA can be used on any operating system. Thus the development and testing phases are made easier and more efficient.

Additional PWA benefits

  • App-like Interface - Supports native app-like navigation and gestures.
  • Push Notifications - Communicate directly with users 24/7
  • Safety - Must be accessed through HTTPS sites
  • Discoverability - Accessible via the web, Google Play Store et App Store (Coming soon)
  • Easy Installation - Faster and easier to install than native apps.
  • SEO - As fast and responsive web page, PWAs have an average SEO score of 85

The Current State of PWAs

Today, Progressive Web Apps are accessible via smartphones and desktops across a variety of browsers (For iOS users, only Safari can be used to add a PWA to the home screen). PWAs also support many of the same features or functions that native apps support.
