Phone apps

You dont need "apps". Your phone has a browser and you can use it to get more info for free without giving access to your personal phone details. I am using my phone to type this message and browse the web. As a techie myself trust me when I say that apps are not worth the effort of finding just use your browser.

Rv.net works fine on a phone browser, campgroundviews.com is great for finding parks, google is google for everything else.

Again the fewer apps the better.
