My phone runs Android 2.3.6. An app transferred to SD card does not appear in apps menu when phone is re-started. The menu shows or displays only those apps in the phone memory.
Android app menu will show only installed apps. Install it first if uninstalled. If that doesn't work, re mount your SD card. If it still doesn't work, move it to another directory and retry.
use the sychronization software "free mobile helper" , Free Mobile Helper allows Windows PC based users to seamlessly control and sync their Android/Ios mobile device.
All the files will be shown through this software.
Use the free apps App2SD from the Google Play Store, it shows the list of moveable apps, list of apps that cannot be moved, list of apps in ext. SD. https://play.google.com/store/apps/details?id=com.a0soft.gphone.app2sd&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5hMHNvZnQuZ3Bob25lLmFwcDJzZCJd
when you boot your android it has to mount the sd card which takes a short time
or you have incompatable apps
or its not properly mounted
hope that helps

I think u should reset ur phone settings as said by Rakesh Mishra
how did you transferred the app to sd card, do you have other apps on sd card and they appear in apps menu?
perhaps the sd card is corrupted and need to be format.
is you memory card mounted correct! if the SD card is not mounted, the apps which are in the memory card will not be shown!
Some apps don't work so well or at all if they're moved to the SD card.
Put your sd into a computer, move the app into a different location, or rename it, and that might help
do you see then with another launcher?
u can reset ur phone settings
