I have experience developing really complex apps (apps involving web services and online databases) and doing an app like this one will be a piece of cake. I am in fact working on a similar project for a different client (much more sophisticated, includes fitness routines, food database, workout database, customizable diet plans with notifications for every meal plan,etc, and it's almost finished.) I already know in my mind all of the steps that will be required to build this app, so time will only be wasted coding the app and documenting the code (I won't need to spend time researching online). If needed, I can provide the design as well from a really good designer friend of mine (free as a favor to me). I guarantee that the project will be delivered in three days. The code will be well structured using Android Developers guidelines and good software engineering principles. I will ensure high re-usability of the code and provide you with at least 6 months of maintenance for your app (in case you need new features/change things around). Just tell me when to start :)
