Karate Academy App Development

I'm looking for a mobile app developer to create an app for my karate academy. The app needs to be available on both iOS and Android platforms. It should primarily serve to:

- Manage student registrations
- Provide training resources (video tutorials and written guides/articles)
- Schedule and notify about classes

Ideal Skills and Experience:
- Experience in mobile app development for both iOS and Android
- Familiarity with building registration and scheduling functionalities
- Ability to integrate video tutorials and written guides within the app
- Strong UI/UX design skills to ensure the app is user-friendly

In addition, I'm looking for a social media manager to promote our academy and the app.
