Diet application for Android

I have a specific diet application that I would like to have implemented for android phones The application will be quite simple. The diet is a 7 day plan and the application will help the user from day 1 to day 7, with visual aids and notifications. Features: - Will provide details on the actual diet - A feature for user to "start" the diet or stop the diet and provide updates to the user as to what they need to be eating - If the user misses a day, they have the option of skipping a day or restarting the diet - The user will be prompted for their weight when they start the die on day 1 and again on day 7 or when they stop the diet. Content regarding the die including the name,will be all provided The appearance of the app must be very professional. More details and features can be discussed.
