Why is my app not showing up?

[Windows Central Question]

I am using a Lumia 530, I have an app installed, it was working fine and I dropped my phone, when I turned it on the app wasn't in my list of apps or in my storage sense anywhere. When I tried to uninstall it I couldn't find it. When I look at it on the marketplace it says it is installed and if I hit view it takes me to my main menu. if I use facebook and open a link the app opens and I am able to use it but its not showing in my phone anywhere so I cant even uninstall it to reinstall it. Is there a known solution to making it reappear or so I can uninstall it?
