Mobile app for fitness startup

I am looking for a freelancer to develop a mobile app for a fitness startup. The app will be database driven and require users to log into their accounts. It will also feature push notifications and a fitness tracker. There will not be a web-version-- only a mobile application available on both iOS and Android platforms. The ideal freelancer would be well-versed in developing app features that support our fitness startup's mission and have experience launching mobile applications. If this project aligns with your interests and skills, please let me know!
