Facebook's Snapchat competitor, Poke, has fallen out of the top position in the App Store on iOS. Not only is it not number one anymore, it's not even present in the top 25 apps. In fact, the app has dropped all the way down to number 34 on the list of top free apps. Snapchat, meanwhile, has increased to number 4.

Right after Poke came out, Snapchat dropped from number 6 to the 8th popular app on the list. Since then, an uptick in its popularity has pushed it to 4th. Facebook's strong marketing ability is likely why Poke was able to obtain the number one spot, but with the app being a bit frustrating to use, according to reviews, it doesn't seem to have staying power.
