This app provides an easy way to choose and automatically generate the Dukan Calendars for both Dukan Diet 1 and Dukan Diet 2 (Nutritional Staircase). It allows the user to create a profile, and, based on the dates generated on the officials Dukan sites, to create the calendar needed for the diet. The user can choose several plans: 1. In case of Dukan Diet 1, the user can choose between 1 day plan, or 5 days plan. 2. In case of the Dukan Diet 2, the user can select the 7 day plan. It also has a measurements tracking part, where the user can keep track of his/her progress. This feature provides a nice graph. For Dukan Diet 1, for 1 day plan, and for Dukan Diet 2, there are notifications a day before the next phase starts (one of the 4 phases of the diet). For Dukan Diet 1, 5 day plan, the user gets notifications a day before the next phase starts and also a day before the next 5 day period.
