Mobile app for fitness start up -- 2

I'm looking for someone to develop a mobile app for my fitness startup. The app should be designed for the Android platform and include social networking features. While I am open to the designer's creativity, I do have some design and branding guidelines to follow. The app should facilitate meaningful user engagement while reflecting my brand’s mission. I am looking for a seasoned developer who can create a stable platform for users to interact within the app. Additionally, the app should be user-friendly and easily navigatable. I am open to discussing further features such as workout tracking and nutritional advice. I am excited to see what kind of creative solutions you come up with!
