Simple Fitness App that connects with PHP website through API

The name for my application is Physique. It is a fitness app based on both mobile(android) and web platforms (PHP & MySQL). The web platform should contain login for admin only and should contain a dashboard through which admin can manage (insert, update, delete) data. And for the mobile application(android), use JAVA as programming language and for the features of this android app, user should be able to register himself/herself as new user and should also have an option to sign in with Facebook and Google also. Login and registration authentication for users should be done using MySQL and PHP. After successful login, the user should be navigated to the home screen where user can select multiple options like view workout routines, food details, count total calories consumed in a day, set timer for workouts and user should also be able to create their own profile. User should be able to set goals like (lose weight, gain weight, etc.) and according to that appropriate diet is to be recommended. In Workout routine section, information about different workout routines should be displayed. In food details section, display the information about foods or products and user should also be able to add the food in the application. While adding the food, enable user to input food/product name, total calorie gained from that food/product and product code (for this put a simple barcode scanner). While counting the calories, enable user to select the food they consumed and also display the recommended calorie to be consumed in a day. And for creating profile, enable user to add their image, personal credentials, age, height, weight, etc.
