When i download apps on my iPhone they don't show up?

Earlier today I downloaded two apps at two different times?

BBM & Kindle for iPhone.

They usually just appear straight on my menu with all the other apps?

But they're not showing up when i go in to the app store to try and open them that way the button won't click down or let me press it sort of thing.

I can't find anywhere to delete the apps from either?

Someone please help, i have never had this problem before.

They might have not been properly downloaded. What iOS are you running?

Please perform a full reboot on the device (power off and on)
try to download apps once again
