Ionic view displaying grey screen v1

I swear this problem is common. I don’t know how to get my ionic app to show on my iphone. It works perfectly fine on ionic serve. I looked everywhere to get help, and it’s still showing me this grey screen.

app.js

var HCapp = angular.module('HCapp',['ionic','ui.router']);

HCapp.config(['$stateProvider','$urlRouterProvider', function($stateProvider, 
$urlRouterProvider){
$stateProvider
 .state('signup', {  
url: '/signup', 
templateUrl: 'views/signup.html'
})

   .state('register',{
url:'/register',
templateUrl: 'views/register.html'
})

    .state('sign-in', {
url:'/sign-in',
templateUrl: 'views/sign-in.html'
  })
 $urlRouterProvider.otherwise('/signup');
 }]);

  HCapp.controller('signCntrl', ['$scope', '$http','$location', function ($scope, $http, 
  $location ){

  $scope.users= {};

   $scope.save = function(){
   // $http.post('http://localhost:3000/sign-in/save', $scope.users)
   $https.post('https://jsc-reactr.fwd.wf/sign-in/save', $scope.users)
   .success(function(response){
   console.log(response);

     $location.path('/home');
    })
   .error(function(response){
   console.log(response);
   });
   }
  }]);

    HCapp.controller('registerCntrl', ['$scope', '$http', '$location',  function ($scope, $http, $location ){

    $scope.save = function(){
   // $http.post('http://localhost:3000/register/save', $scope.register)
   $https.post('https://jsc-reactr.fwd.wf/register/save', $scope.register)
   .success(function(response){
    console.log(response);
   $location.path('/questions');
    })
    .error(function(response){
    console.log(response);
   });
   }
    }]);

What did you do to debug yet?

Did you remote debug the app on your iPhone? Check https://ionic.zone/debug/remote-debug-your-app#ios for instructions, then look at the console and network tabs for errors.
