App for graduate program

I am in search of a seasoned app developer with impressive skills in creating user-friendly and attractive mobile applications, primarily for educational platforms. Though I've skipped the optional platform requirement, it's important that the app should be functional across iOS, Android, and Web-based platforms, widening accessibility for its users.

Key Requirements:

- Developers should have prior experience in designing and developing mobile applications that incorporate elegant user interfaces and smooth navigation.
- The developer should propose a comprehensive application plan that highlights the important milestones, details of functionalities, design ideas, and the possible challenges and solutions.

Desired Functionalities (though not explicitly specified):

- Users Account creation and its management
- An option for users to check in and know they are on track on a weekly basis
- Inclusion of learning and training modules

Please note, freelancers who offer detailed project proposals showcasing their understanding and approach to achieving these functionalities will be highly considered for the job. Interested applicants please provide your detailed proposal, outlining your strategy and timeframe to complete this assignment.
