It’s been two years since Google introduced Instant Apps, a Google Play feature that lets users try an app without downloading it. While the format has been mostly popular with game developers, today, Google announced at its annual I/O developer conference that Instant Apps will soon support ARCore, allowing users to interact with augmented reality apps without having to download them.

The experience will also be more closely integrated with search rather than within Google Play or in-app advertisements. For example, soon, users will be able to search for shoppable items and see a link to an Instant App that lets them place the products in front of them in augmented reality — much like the Ikea Place app that lets you virtually trial furniture pieces in your home.
