how to use ionic.Platform

I'm very new to using ionic/AngularJS and I was wondering how exactly to use ionic.Platform to print the current device. Right now I have 

var currentPlatform = ionic.Platform.platform();

in my main.html ctrl. Is there a way to send it to the html page, or am I approaching it completely wrong?

from your controller data send to view use application model $scope , means just assign your variable to scope variable and get it directly where you call your controller in view.

Example :

    angular.module('scopeExample', ['ionic'])
    .controller('MyController', ['$scope', function($scope) {
          var currentPlatform = ionic.Platform.platform();  
          $scope.currentPlatform = currentPlatform;
    }]);

and in view you access 

      <body ng-app="scopeExample">
        <ion-pane>
          <ion-header-bar class="bar-stable">
            <h1 class="title">Ionic Blank Starter</h1>
          </ion-header-bar>
          <ion-content ng-controller="MyController">
           {{currentPlatform }}
          </ion-content>
        </ion-pane>
      </body>
