Step 1. Get web token from where you stored it in jstorage (in myApp.js) 
(see Authenticate with Moodle from a mobile app for how to store the session token) 
 moodleUrl = 'https://moodle.yourwebsite.com/webservice/rest/server.php';
session = $.jStorage.get('session', ''); // syntax: $.jStorage.get(keyname, "default value")
moodlewsrestformat = 'json';
wstoken = session;
concatUrl = moodleUrl + '?moodlewsrestformat=' + moodlewsrestformat + '&wstoken=' + wstoken + '&wsfunction=';
Step 2. create Angular module (in myApp.js)
angular.module('myApp.controllers', []);
var myApp = angular.module('myApp', ['ui.bootstrap']);
(the ui.bootstrap part is optional depending on whether you are using Bootstrap UI elements)
Step 3. create controllers (in myApp.js)
myApp.controller('myFirstCtrl', function ($scope, $http) {
    url = concatUrl + 'local_appname_ws_function_name';
    $http.get(url).then(function (response) {
        $scope.items = response.data;
    })
});
myApp.controller('mySecondCtrl', function ($scope, $http) {
    url = concatUrl + 'local_appname_ws_function_name';
    $http.get(url).then(function (response) {
        $scope.things = response.data;
    })
});
Step 4. create ng-app instance in html (in index.html of your mobile app)
<body>
    <div class="overlay"> </div>
    <div data-role="page" id="welcome-page">
        <div data-role="header" class="header">
            <h1 id="app-title">
                App title
            </h1>
        </div>
        <div role="main" id="main" class="ui-content scroll" ng-app="myApp">
   <!--ng-repeat elements will go here-->
</div>
Step 5. Create one ng-repeat element for each controller (in index.html) 
<div role="main" id="main" class="ui-content scroll" ng-app="myApp">
    <div data-role="content" class="pane" id="">
        <h2>Your Items</h2>
        <div class="page-wrap scroll" ng-controller="myFirstCtrl">
            <div ng-repeat="item in items | orderBy : 'item.name'" id="{{item.id}}">
                <div class="item-data">
                    {{item.name}}<br />
                     <time datetime="{{item.date}}">{{item.date}}</time>
                </div>
            </div>
        </div>
    </div>
    <div data-role="content" class="pane" id="">
        <h2>Your Things</h2>
        <div class="page-wrap scroll" ng-controller="mySecondCtrl">
            <div ng-repeat="thing in things | orderBy : 'thing.name'" id="{{thing.id}}">
                <div class="thing-data">
                    {{thing.name}}<br />
                     <time datetime="{{thing.date}}">{{thing.date}}</time>
                </div>
            </div>
        </div>
    </div>  
</div>
