On Wednesday, a handful of Facebook users were tweeting about a new feature, which seems to only be available in limited markets, that might be familiar to some users. The new program lets users set a time to make their posts disappear. The timing can occur anywhere from an hour to a week in the future.

Sound familiar, Snapchat users?

A Facebook spokesperson confirmed that the social media giant is “running a small pilot of a feature on Facebook for iOS that lets people schedule the deletion of their posts in advance.”

Facebook’s beta tests come just a week after updates to its standalone Slingshot app, which was released in June. Facebook reported that it was tweaking Slingshot’s single message profile. This update would no longer require users to send a return message in order to unlock any photo or video sent to them by a friend. It’s an attempt to streamline the app profile and increase its popularity.

These innovations began when start-up Snapchat spurned Facebook’s $3 billion takeover offer last year. Since then, the messaging service has seen a number of other tech rivals try to duplicate the startup’s disappearing message model. Besides the Facebook release of Slingshot, Yahoo paid an undisclosed amount for a similar app called Blink to be introduced later this year.

With imitation being the sincerest from of flattery, it’s hard to blame these other companies for trying to recreate Snapchat’s service. Currently, the startup’s latest round of venture capital funding reportedly values it at about $10 billion. The app is said to have more than 100 million monthly active users and it regularly ranks atop the Apple iTunes store’s most popular free downloadable apps.
