I installed it at some point, but then I wasn't sure how it was any different from the data usage settings in the app properties? There are options to disable Wi-Fi and data there too.

As per OP, using NRF you can fine-tune what is blocked and what is not. Say, for a game with an online component you would want to allow the game to access game servers, but not the advertisement servers.
