The default behaviour of the back button is as follows: Go back in history - if the history stack is empty -> exit the app.

So you should check the $state you are in, when you tap the hardware back button.

With the following code (placed in the run function of your module) you can overwrite the default behaviour. For example you can disable the app exit like this:

$ionicPlatform.registerBackButtonAction(function (event) {
  if($state.current.name=="app.home"){
    navigator.app.exitApp(); //<-- remove this line to disable the exit
  }
  else {
    navigator.app.backHistory();
  }
}, 100);

See the documentation for $ionicPlatform.
