Slingshot, Facebook’s new Snapchat competitor, has today been made available internationally on Android and iOS. The free service, which first made its debut in the U.S. last week, allows users to send “shots” containing pictures or videos to each other — but only after they’ve sent a shot back. Slingshot is Facebook’s bid to cash in on the popularity of sharing services like Snapchat, but it isn’t exactly a Snapchat clone. User can share shots that contain pictures and videos and they are automatically deleted after being viewed, but you cannot see those shots unless you’re willing to share one of your own.
