Native(?) Geolocation on posts using iOS app

Hi.
I’m truly sorry if this is something very obvious or already covered somewhere else. Right know I’m kind of overwhelmed with what WordPress became and how much information there is.
I first used wordpress in version 1.5 and until 2.xx. I’m not a professional designer coder.

Here’s my question:
I decided to make a new blog (self hosted, quirkie.net) and I intend to use GeoLocation for each post. I saw that the official IOS app has a location option. I activated it in the option in the app, made a test post and even though I can see the location when using the app (while editing the post) I can’t find a way to display the location in the post itself.

Is there a native support/option for this? Which php command should I use to retrieve the post location?
Is there any plugins that use the information from the IOS app?
And another different question: is there a way to display one map with all the locations from each post?

I need a simple way to add the location to each post, via iOS app and web.
Thanks for everything.
