Dieta FODMAP is an Android app developed by Wanderley Melo that helps users manage the symptoms of Irritable Bowel Syndrome (IBS) by providing a list of high, moderate, and low FODMAP foods. FODMAPs are fermentable oligosaccharides, disaccharides, monosaccharides, and polyols that are poorly absorbed by the human digestive tract and can cause intestinal discomfort. The app utilizes a "traffic light system" to indicate the FODMAP tolerance levels of foods: red for high, yellow for moderate, and green for low.

The app also features an icon next to each food item that links to its Wikipedia page, and a tutorial on how to use the app can be accessed from the menu bar. However, it is important to note that the app should be used in conjunction with a medical consultation and guidance from a registered dietitian. The app is free and falls under the Lifestyle category, specifically Health & Fitness.
