Instagram is testing a standalone app for private messages called Direct, a first step towards removing messaging features from the core app. The app will let you create and share stories, and give you access to exclusive filters, Boomerang and other creative tools on Instagram. And, of course, your Instagram friends are added instantly to the Instagram Direct app. The move is similar to what Facebook did with its private messaging feature in 2014. For now, the app is only available in Uruguay, Chile, Turkey, Italy, Portugal and Israel.
