I don't use it for Iphone but I'm sure it's the same as android version. It's quick and easy to connect to forums as it doesn't load up all the extra stuff, you're also able to login post quote etc. It's quick access to the forums to check new threads and post without using up as much memory as the browser would loading everything up. I would think the data usage on it is not much. Check the images of the app program and see if you like.
