900% more Google user homescreens now sport the PWA

Aug 18, 2022 (CAPE TOWN, South Africa) — The Google I/O PWA has been revolutionary. 900% more people are saving the app to their homescreen, and many enable notifications.

Google I/O has invested in building a single-page Progressive Web App (PWA) with notable results. The Google PWA was a great move and a good example of the PWA success waiting for many companies.

More time spent on the app

The PWA has brought in more engagement than the Android app. Users spent an average of 2:40 minutes on Android, that has jumped to 4:06 minutes on the PWA.

Service worker caching allows for a 450ms faster first paint. Users can start using the app in a reduced amount of time. When users do not have to wait around, they tend to be more active and happy on the platform.

Increased home screen saves

Add to home screen saves increased by a whopping 900% compared to the numbers in 2015. With more users adding the app to their screens, return visits are up and the PWA is increasing retention.

An icon on the home screen provides a constant reminder to people of the brand. When they need the service, they are just one tap away.

It is easy to add the app, and users are more likely to decide to do so. There is not a big cost to download or store the PWA. Many users prefer it.

Offline use and notification opt-in

Offline users generated 11k page views. 3.8% of users opted to go offline, but amazingly were still able to view pages. People can carry on browsing even when a connection is unreliable.

Notably, developers of PWAs have found that users can browse while they are traveling through tunnels or experiencing other disruptions to their connections.


  • 50% of signed-in users opted for notifications. This allowed Google I/O to re-engage users and remind them to return to the app.

  • 536k notifications were sent to users and 12% of those were successful in bringing users back to the app.

  • 99% of users' browsers supported the web components polyfills. That means that this technology hardly alienated anyone.

Google's implementation of a Progressive Web App has been characterized by success. Users are loving the new mobile experience.
