Go to your dashboard on heroku  Select the app  There is a dynos section  Just pull the sliders for the dynos down   a decrease in dynos is to the left   to the number of dynos you want to be running  The slider goes to 0  Then save your changes  Boom   According to the comment below  there is a pencil icon that needs to be clicked to accomplish this  I have not checked - but am putting it here in case it helps

You might have to be more specific and specify the app name as well  this is the name of the app as you have it in heroku   For example   heroku ps scale web 0 --app myAppName    Otherwise you might get the following message      heroku ps scale web 0 Scaling dynos    failed       No app specified        Run this command from an app folder or specify which app to use with --app APP
