Please take a look at this example here. It 3 is a simple example of a count up! Which 2 I think you could easily modify to create 1 a count down.

http://jsfiddle.net/ganarajpr/LQGE2/

JavaScript code:

function AlbumCtrl($scope,$timeout) {
    $scope.counter = 0;
    $scope.onTimeout = function(){
        $scope.counter++;
        mytimeout = $timeout($scope.onTimeout,1000);
    }
    var mytimeout = $timeout($scope.onTimeout,1000);

    $scope.stop = function(){
        $timeout.cancel(mytimeout);
    }
}

As of version 1.3 there's a service in module 10 ng: $interval

function countController($scope, $interval){
    $scope.countDown = 10;    
    $interval(function(){console.log($scope.countDown--)},1000,0);
}

Use with caution:

Note: Intervals created 9 by this service must be explicitly destroyed when 8 you are finished with them. In particular 7 they are not automatically destroyed when 6 a controller's scope or a directive's element 5 are destroyed. You should take this into 4 consideration and make sure to always 3 cancel the interval at the appropriate moment. See the 2 example below for more details on how and 1 when to do this.

From: Angular's official documentation.

You should use $scope.$apply() when you execute an angular 1 expression from outside of the angular framework.

function countController($scope){
    $scope.countDown = 10;    
    var timer = setInterval(function(){
        $scope.countDown--;
        $scope.$apply();
        console.log($scope.countDown);
    }, 1000);  
}

I updated Mr. ganaraj answer to show stop 3 and resume functionality and added angular 2 js filter to format countdown timer

it is here on jsFiddle

controller 1 code

'use strict';
var myApp = angular.module('myApp', []);
myApp.controller('AlbumCtrl', function($scope,$timeout) {
    $scope.counter = 0;
    $scope.stopped = false;
    $scope.buttonText='Stop';
    $scope.onTimeout = function(){
        $scope.counter++;
        mytimeout = $timeout($scope.onTimeout,1000);
    }
    var mytimeout = $timeout($scope.onTimeout,1000);
    $scope.takeAction = function(){
        if(!$scope.stopped){
            $timeout.cancel(mytimeout);
            $scope.buttonText='Resume';
        }
        else
        {
            mytimeout = $timeout($scope.onTimeout,1000);
            $scope.buttonText='Stop';
        }
            $scope.stopped=!$scope.stopped;
    }   
});

filter-code adapted from RobG from stackoverflow

myApp.filter('formatTimer', function() {
  return function(input)
    {
        function z(n) {return (n<10? '0' : '') + n;}
        var seconds = input % 60;
        var minutes = Math.floor(input / 60);
        var hours = Math.floor(minutes / 60);
        return (z(hours) +':'+z(minutes)+':'+z(seconds));
    };
});

It might help to "How to write the code 1 for countdown watch in AngularJS"

Step 1 : HTML Code-sample

<div ng-app ng-controller="ExampleCtrl">
    <div ng-show="countDown_text > 0">Your password is expired in 180 Seconds.</div>
    <div ng-show="countDown_text > 0">Seconds left {{countDown_text}}</div>
    <div ng-show="countDown_text == 0">Your password is expired!.</div>
</div>

Step 2 : The AngulaJs code-sample

function ExampleCtrl($scope, $timeout) {
  var countDowner, countDown = 10;
  countDowner = function() {
    if (countDown < 0) {
      $("#warning").fadeOut(2000);
      countDown = 0;
      return; // quit
    } else {
      $scope.countDown_text = countDown; // update scope
      countDown--; // -1
      $timeout(countDowner, 1000); // loop it again
    }
  };

  $scope.countDown_text = countDown;
  countDowner()
}

The way I did , it works!

*angular version 1.5.8 and above.

Angular code

var app = angular.module('counter', []);

app.controller('MainCtrl', function($scope, $interval) {
  var decrementCountdown = function() {
    $scope.countdown -= 1;
    if ($scope.countdown < 1) {
      $scope.message = "timed out";
    }
  };
  var startCountDown = function() {
    $interval(decrementCountdown, 1000, $scope.countdown)
  };
  $scope.countdown = 100;
  startCountDown();
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.10/angular.min.js"></script>



<body ng-app="counter" ng-controller="MainCtrl">
  {{countdown}} {{message}}
</body>

You probably didn't declare your module 9 correctly, or you put the function before 8 the module is declared (safe rule is to 7 put angular module after the body, once 6 all the page is loaded). Since you're using 5 angularjs, then you should use $interval (angularjs 4 equivalence to setInterval which is a windows 3 service).

Here is a working solution:

angular.module('count', [])
  .controller('countController', function($scope, $interval) {
    $scope.countDown = 10;
    $interval(function() {
      console.log($scope.countDown--);
    }, 1000, $scope.countDown);
  });

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.1/angular.min.js"></script>


<body>
  <div ng-app="count" ng-controller="countController"> {{countDown}} </div>
</body>

Note: it 2 stops at 0 in the html view, but at 1 in 1 the console.log, can you figure out why? ;)
