My galaxy s4 wont let me open my apps

[smm13]

I have a galaxy s4 and everytime I go to my home page none of my apps show up I go to my apps and it says I have nothing download but when I go to my Play Store it says that they're all installed but it doesn't give me the option to open them I don't understand why it is doing this. So basically when I go to my place store they say that they're all downloaded and then when I go to my home page and click on the button that takes you to all your apps and I try to find the apps that I downloaded it says that I have nothing download it

Hi, what apps are you trying to download? some apps are plugins for other apps and don't create an app in your phone.
