(CNN) - Some of you might remember the old Facebook "poke."
You know, the little nudge you'd give someone to remind them you existed.
Well, the social media site has re-launched "poke" as an app, and it's not getting great reviews. In fact, some are calling it a dud.
Basically, the new poke feature copies Snapchat, the app where users' messages self-destruct.
A research expert from Altimeter Group claims Facebook just created the app to keep up with the younger users, but that the app is very badly done.
The app hit number one in Apple's App Store on day one, it fell out of the top 50 just as quickly, according to an article from Fortune magazine, a CNN entity.
