Deleted App in Error

Probably you want to know if an app is deleted by mistake then where to find the same.

Open App Store > Tap on your Pic (Top Left Hand Side) > Purchased > My Purchases > Tap on Not on this iPhone

This is the list of Apps that are currently not on your device.

If you can't figure out what app is missing, you probably didn't use it very often... Do you really need it?
