You are not correct. Each app that uses Facebook login MUST declare custom URL so that you can come back to it when you are transferred to FB app (it has a syntax "fb...", where "..." are replaced with FB app id). So you can assume that each and every application that uses FB login has custom URL.

Now Tinder declares 3 custom URLs actually: "tinder", "fb464891386855067", "tinderdebug".
