Build an Algorithm and iPhone/Andriod app

I need a an original algorithm that will perform a calculation and reveal the results via mobile app. The app will be a Health and Fitness iPhone and Android app the user will enter information > algorithm figures out final calories needed based on the user entered information and “Tdee calculator” > grabs cooking recipe from database > show result App name: Cayenne The Fitness App Category: Health and Fitness The Algorithm: The ALGOR takes the amount of loss/gain calories calculated by a standard “Tdee calculator” - the amount of calories burned during sex + the amount of time you spend sleeping - the amount of calories accumulated by how much alcohol consumed per week = ____ The App: • User can register with Facebook, Twitter, Instagram (switches to apps not just straight to browser) • User can change to Mufti-language • User can check-in their location via Facebook, Posse, Yelp and Foursquare • User can enter their wake time and sleep time. • User can see video/instructions on how to do a exercise routine. • Ability to see how many reps and sets were done on a certain exercise previously.. to compare progress (the client has to have an option to record their exercise stats ) They should also be able to see their progress from last time underneath the current exercise • User can track calories for random foods. • User can take a photo and video of foods. • User can choose an exercise by selecting a body graphic and touching a targeted area arms-back-abs-chest etc. • User can Social share everything, photos, exercise results. • User can enter and records every detail of your workout, including duration, distance, pace, speed, elevation, calories burned, and route traveled on an interactive map. The app compiles and crunches this data to create a comprehensive workout history. • User can use a Stop watch timer to time themselves in workout sets • User can record reps and sets in history (the user has to have an option to record their exercise stats) • User can choose an exercise by equipment they require kettle- bells, dumbbells, body weight, etc. • User can choose an exercise by routines for various goals, ie,.. fat-loss, strength, ab definition etc. • User is able to see their stats from last recorded workout right underneath the current exercise stats. • User can see photo images/instructions on how to do a exercise routine. • The app supply a “meal plan and recipe” together from server based on “Algorithm” • User will be assign meal plans and recipes based on Algorithm The Server: - must be able to add more features in the future - must be built on open source technology NOT MS • Admin needs to add and take out meal plans and recipes • Admin needs to add and take out videos and video instructions • Admin needs to add and delete users • Admin needs to see all user information • Admin needs to send push notifications to all users or single user • Admin needs to track users via GPS • Admin needs to export all users info, social and all info entered via app • Admin needs to track apps who, what, where analytics
