A few weeks after announcing that iOS support was on the way, Google’s cloud gaming service now supports the iPhone and iPad. As expected, the company is using a web app to access the service. Google also says that you need to update to iOS 14.3, the latest iOS update that was released earlier this week.

If you want to try it out with a free or paid Stadia account, you can head over to stadia.google.com from your iOS device. Log in to your Google account, add a shortcut to your home screen and open the web app.
