1. Reliable: Progressive Web Apps pre-caches the key resources eliminating the dependency on the network, thereby, making sure that the users are able to get an instant and reliable experience. There is a service worker, which is a script written in JavaScript and it runs in the background separate from a webpage.

2. Fast In a research by Google, it was found that 53% of users will abandon a website if it takes 3 seconds to load or respond. Progressive web apps are fast and are able to enhance the overall performance. This will help the businesses to retain the users and improve conversions.

3. Engaging Progressive web apps remain on the user’s home screen and don’t require app store. They are able to provide full-screen experience to the users by using the web app manifest file. The web app manifest is a JSON file which is used to instruct the browser about the web application and how it should behave when installing on the user’s mobile device or desktop. The web manifest file is necessary as Chrome requires it in order to show the prompt “Add to Home Screen”.
