Yoga app for android and iphone

I am looking for a developer to create an Android and iOS app for yoga enthusiasts. The key feature of this app will be a customizable workout planner, with beginner-friendly poses, to help users progress with their yoga journey. Additionally, the app will feature a progress tracking element to chart and monitor progress, providing motivation and support. To cover the costs of the development, the app will combine free-to-download access with in-app purchase options. To further engage users with each other, the app will include social features that will enable people to share their progress and join group challenges. Therefore, I am looking for someone who has expertise in both mobile development (Android & iOS) and social media integration.
