iPhone, iPad etc Apps - What do you use

Ok, thanks much for the info...

Seems like there's always 'something' missing from trip planning on the computer to putting live in the car... smart phone are catching up, with the .gpx files, but still not there yet, IMNSHO... heheh...

And the battle continues....

Always seems there's a "block" somewhere in the process:

 

I am looking for an Android app to locate camping spots while on the road. I found three which I think look promising and was wondering if anyone has used one of these and what you think. All three are also available for iPhone so all experiences are welcome.

We Camp Here Campground Search
https://play.google.com/store/apps/details?id=com.wecamphere.wecamphere
$4, only lists campgrounds so you don't have to sort through gas stations and RV dealers. It is connected to www.wecamphere.com and collects and displays user reviews.

Camp Finder - Campgrounds
https://play.google.com/store/apps/details?id=com.campingroadtrip.campfinder
$3, claims to list campgrounds of all types. Connected to www.CampingRoadTrip.com which also does user reviews.

Allstays Camp and RV - Campground Plus
https://play.google.com/store/apps/details?id=com.allstays.app.camprv
$10, includes not only campgrounds but supply stores, truck stops, rest stops, RV rentals and dealers etc. One claim they make is that a lot of stuff is stored in the phone so an internet connection is not necessary all the time. Connected to the www.allstays.com website.

Edit: I found the thread about Allstays and it sounds like there is some good experience, but that info is a couple of years old and things change fast in this arena.
