Write an iPhone, iPad and Apple Watch Application

Keep note: Freelancer will need to know how to code in Swift, Java and C++ for future project reasons. The application we are planning to build is a 7 Minute Workout App. We plan to go up against the "big dogs" in the 7 Minute Workout market, thus also meaning the fitness and health industry. The application will need to have a back end api server (login page) and all of the many features packed into a typical 7 Minute Workout app. I also have an animator that will be animating 360 3D animations of a personal trainer demonstrating the workout for the user while the user is on the workout screen. I am not able to fund for the project. So my proposal deal was offering 30% of the app profits to the developer and once the profits come in to pay the developer at large, we can work on adding platforms to the application. An example would be Android and Apple TV. Make sure you know how to code for iPhone, iPad, Apple Watch, Apple TV, iMac, Android and Windows (C++). Again, I would be giving you a percentage of the app's profit. Say "CODE RED" at the beginning of your application if you have read the entire project description. The application is estimated to have 10,000,000 - 50,000,000 downloads on one platform, this is based for what is seen on the android/google platform. The average percentage of people who purchase in app-transactions is 5%. If you take the in-app purchase that will be offered in the app and remove fees and multiply the 5% population by 2.30 (in-app transaction), you would get $1,150,000, then take 30% of that (your part of the money) and you would get $345,000. Tell me if you agree to working on this project with the plan of you getting 30% without paying during development. I hope you really consider.
