And because I’m new I don’t know where to start from(getting information), fox example how to tell app when i press button in app to make a call. Please help I’m in a little bit of pickle

Meteor supports Cordova for mobile development, you should get familiar with it. This link explains how to add mobile support to a Meteor application and in particular this article explains how to make phone calls from your app. Note that some additional permission have to be provided so have a look at App.accessRule() and better still, get yourself familiar with mobile configurations parameters.

This might sound a lot but it integrates with ease when you get used to!

Another very good mobile starter blog is here:
