  • Q: What are some examples of mobile apps that are Progressive Web Apps?
  • A: Progressive Web Apps (PWAs) are mobile-optimized web applications that can be accessed through a web browser, but offer a native-app like experience. Some well-known examples of Progressive Web Apps include:
    • Twitter Lite.
    • Flipkart Lite
    • OLX
    • Forbes
    • Financial Times
    • Airbnb.
    • Pinterest
    • Trivago
    • Alibaba
    • Instagram Lite
  • These apps use modern web technologies like Service Workers and Web App Manifests to provide a fast, reliable, and engaging experience, even when offline or with a slow internet connection. PWAs can also be installed on the home screen of a device, just like a native app, providing users with easy access to the app and a seamless experience.

  • A progressive web application (PWA), commonly known as a progressive web app, is a type of application software delivered through the web, built using common web technologies including HTML, CSS, JavaScript, and WebAssembly. It is intended to work on any platform with a standards-compliant browser, including desktop and mobile devices.

    Since a progressive web app is a type of webpage or website known as a web application, they do not require separate bundling or distribution. Developers can simply publish the web application online, ensure that it meets baseline installation requirements, and users will be able to add the application to their home screen. Publishing the app to digital distribution systems like Apple App Store or Google Play is optional.

    As of 2021, PWA features are supported to varying degrees by Google Chrome, Apple Safari, Firefox for Android, and Microsoft Edge but not by Firefox for desktop.

  • In 2017, Twitter released Twitter Lite, a PWA alternative to the official native Android and iOS apps. According to Twitter, Twitter Lite consumed only 1-3% of the size of the native apps. In July 2019 Twitter started serving all website users to Twitter Lite by default. On June 1, 2020, Twitter deactivated the legacy website layout, leaving the progressive web app version as the only option. Starbucks provides a PWA that is 99.84% smaller than its equivalent iOS app. After deploying its PWA, Starbucks doubled the number of online orders, with desktop users ordering at about the same rate as mobile app users.

    Several businesses highlight significant improvements in a wide variety of key performance indicators after PWA implementation, like increased time spent on page, conversions, or revenue.
