The push into the cloud is taking more shape, with Google teasing the future with their announcement of the testing of Instant Apps - a feature that will run select Android apps, without needing to install them.
Google makes Instant Apps work by being a smaller version of their native Android apps that run as soon as you tap their URL, without an installation. Once you've closed the app, it will disappear from your phone with no memory of icons on your desktop, but stays in your phone cache for a few hours if you open the link again.
A few applications work with Instant Apps, including Buzzfeed, Wish, Periscope, and Viki. Google Play software engineer Aurash Mahbod explains: "By collecting user feedback and iterating on the product, we'll be able to expand the experience to more apps and more users".
Why would Instant Apps be useful? For the apps you might install once, it is perfect - no installation, and it doesn't take additional space on your storage. You can quickly install the app without going to the Play Store, without installing it - if it's not good, no installation. Move onto the next, find something more suitable, try it out - and then download it.
