Snapchat’s disappearing message act might be more popular than we think. Facebook is currently testing a similar feature in its Messenger app, allowing you to send messages that later disappear.
If
 you’re using Facebook Messenger in France, you can tap an hourglass 
icon in the app to turn the feature on. Tap it again and the feature is 
off. Although you’ll still be able to see the text box where the message
 first appeared, there won’t be any content to view.
According to Alex Kantrowitz at BuzzFeed,
 the new feature allows you to choose to have your messages disappear an
 hour after sending them. In a statement from a Facebook spokeswoman, 
“Starting today, we’re conducting a small test in France of a feature 
that allows people to send messages that disappear an hour after they’re
 sent. Disappearing messages gives people another fun option to choose 
from when they communicate on Messenger. We look forward to hearing 
people’s feedback as they give it a try.”
The
 feature is a move that directly takes aim at Snapchat, one of the 
platform’s biggest competitors. While Snapchat claims only a tenth of 
the user base Facebook claims, the chat application is quickly closing 
in on Facebook with over 6 billion video views daily.
The
 Facebook Messenger feature is currently being tested for iOS and 
Android users, but may or may not become available outside of France. 
Facebook Messenger users who like the Snapchat attribute might find this
 a welcome addition. If it gets rolled out, it would follow a number of 
recent Messenger updates, including the ability to send video and 
GIF replies, send payments, as well as plans to include a virtual 
assistant and purchase tracking capabilities.
