Facebook on Monday briefly listed its unannounced Slingshot app on the Malaysian App Store; however the app was soon pulled down from the store. The Verge quotes a Facebook spokesperson who confirmed the accidental listing of the unreleased app and said, "Earlier today [Monday], we accidentally released a version of Slingshot, a new app we're working on. With Slingshot, you'll be able to share everyday moments with lots of people at once. It'll be ready soon and we're excited for you to try it out."
Notably, Facebook's new ephemeral chat app Slingshot, unlike Snapchat and other chat services, forces a user to send an image or 'sling' [as Facebook calls it] in order to view an image. The feature in the Slingshot app is seen as a move to increase the user involvement in the app.
Other features in the app include the ability to write captions and make drawings on the images and video messages sent by a user, something already found on Snapchat. The Slingshot app also offers users viewing a message the ability to send a reaction to an image, with the React button to send the reaction to an image. The app maintaining its ephemeral nature deletes an image once it is swiped away by the user.
