Aha!!
Just google Wikicamps.....or search for the app. There's an apple and an android version and you can use it offline.
It's about $7 or so and is invaluable when looking for places to stay...caravan parks, free camps, with or without dogs, dump points ect......all info that affects your choice of a place to stay.
There are photos, prices, comments etc that are updated by travellers so they're not generally too biased.
Mapping, trip planning etc etc.
Look out, it's addictive.
CampMate is another one...not quite as up to date ...but very useful for similar use....free I think but just for android.
Have fun!
