How to check - is it possible to use such an application name?

Question

Apple App Store

I have an idea for a social app. The name popped into my head. The name is a well-known dialect (not just a set of letters) and was used for the title of some movie in 2012, also google gives the result that there is some service with this name for buying ads (my idea has nothing to do with this) and the game 70s.
Can a similar name be used? Is there a service to check the possibility of use?
