Key Features:
- Typing Speed Test: Users should be able to check their typing speed through a dedicated test within the app.
- Real-time Feedback: The app should highlight mistakes as users type.

Practice Options:
- Random Paragraphs: The app should present users with random paragraphs to type, providing a diverse range of practice content.

Ideal Skills and Experience:
- Proficiency in cross-platform app development.
- Experience with UI/UX design for educational apps.
- Understanding of real-time data processing in apps.
- Prior work with typing or educational apps would be a plus.
