Show related records of a custom object on a detail page for that custom object

Hi

I have a custom object with a master detail relationship to the Contact object. 

I would like to have, on the custom object's record detail page, a list of all other records for that custom object's record that are related to the linked contact. 
Like a related list, but for records on the same object, not a child object.

I found a way to show a related list for another object linked to the contact, but not on the same object
<apex:page standardcontroller="app__c">
<apex:relatedList subject="{!app__c.Contact__c}" list="apps"/>
</apex:page>

Org is still in Classic

You need standard controller and extension both.

VF code:- 
<apex:page standardcontroller="app__c" extensions="showAppRecords">
<apex:repeat var ="r" value="{!records}">
{!r.Name}
</apex:repeat>
</apex:page>
Exentsion :-
  
public class showAppRecords{

public List<app__c> records{get;set;}

public showAppRecords(StandardController con){
string appId=ApexPages.currentPage().getParameters().get('id');
records=[Select id, name from app__c where Contact__c =:appId ];
}

}
Hope this works.

Hi Ashishk, unfortunately that solution didn't work, I go errors on line 5 of the extension.

Hi Ajay, thank you, that solution provided the block with table containing header. However no records listed. 

any ideas?
