Simple Flashcard App Development

I'm looking for a developer to create a basic flashcard application, reminiscent of Anki, but without its complexity. This cross-platform app should cater to students, allowing them to login, and purchase various flashcard courses.

Key Features:
- Cross-platform compatibility (Android and iOS)
- Simple, user-friendly interface
- Student login via Email and password
- Course purchase using Credit/Debit card

Ideal Skills:
- Proficient in Android and iOS app development
- Experience with implementing secure login systems
- Knowledge of integrating payment gateways

This project requires a developer who can create a simple yet efficient application, with a clear understanding of the needs of a student user base.
