After your hard day of working and eating, you probably be wondering how many calories you consumed. Like a search engine you would type in the food you ate, and it would give you an estimate of the calories you consumed. Maybe the app would also include for you to input your present age and weight if the food is organic or not etc.. Then the app could also include a chart to keep track of your daily calories consumed and then the app could also have a list of what to eat and what not to eat to so you can try to eat healthier.
