The only treatment available for celiac disease and other gluten-related disorders remains a lifelong gluten-free diet. Knowledge of the gluten content in foods is one of the crucial factors for dietary compliance which helps prevent future complications related to gluten consumption. In order to help patients cope with the burdens of the gluten-free diet, a mobile app was created. The bezGlutenu mobile app (Polish „Gluten-Free”) is the first mobile app in Poland serving as a database of every product licensed with the Crossed Grain symbol available on the Polish Market. This mobile app can help patients with the management of the gluten-free diet.
