Mobile app for fitness startup

I'm looking to develop a mobile app for a fitness startup. The app must be compatible with Android and feature fitness tracking. I already have a detailed design of how I'd like the app to look, so the process of developing this should go relatively quickly. Fitness tracking will be the main feature of the app, allowing users to track their progress and view their results. If you think you have the skill set to complete this project, please contact me. I'm excited to hear what you have to say!
