Android Instant Apps have finally arrived. The concept of Instant Apps has existed for quite some time but Google never really took it further until now. The tech giant has finally listed the “Try It Now” button in the Play Store listings. It announced the integration yesterday and it is now live on the Play Store. The new Try It Now button will let you test drive apps before going ahead and installing them. This way you can check out an app and don’t waste time for installation and un-installation.

Not just Play Store, you can try Instant Apps from any listing on Google search, social media websites, messaging, and other links without the need to install them. For now, there are just limited apps that support the functionality. The apps that support “Instant Apps” feature are BuzzFeed, NYTimes (Crossword), Hollar, Red Bull, Skyscanner, and Onefootball Live Soccer Scores. These apps can be tried by the users without installing them.
