`ng-cloak` doesn't work if your scripts are not in the head. Also, you should not use the less.js script in production, it is unbelievably slow. You should compile the LESS files into CSS files before deploying to a live site.

Add

     .ng-cloak {display: none !important;}

To your css. You've already added the ng-cloak class to your element, angular will remove it once it is done loading.
