There are strengths and weaknesses in error prevention/correction in this design. Though there are many text boxes to fill in while entering foods, autocompletion and predictions about the user's entries can easily help them fill in the fields quickly (also an efficiency benefit) and generally without error. Nonetheless, users may also ignore the autocompletion or forget to fill in values on their own. Even worse, they may not realize that they did not change the predicted value and not know to correct the error. In most cases, errors are easily recovered from. Food entries, for instance, can be moved around and deleted with ease. Any errors made with the budget can be changed on the budget page. Modal dialog boxes also help with error prevention. They prompt the user for necessary information and, because of a faded background, clearly indicate to the user that a new mode has been entered.
