mobile app for physical activity and training in the gym around the menstrual cycle

I'm looking to develop a mobile app for physical activity and training in the gym around the menstrual cycle. The app should be designed for both iOS and Android users. The app should have features such as tracking the menstrual cycle and providing workout plans as well as hormone information which users are able to access in order to understand why their body is responding the way it does. Additionally, I am looking for the design of the app to be minimalistic and clean with a focus on usability. If you are well-versed in mobile app development and can create an app that meets all of these requirements I'd love to hear from you!
