Mobile app

I'm looking to develop a mobile app for Android devices with a primary function of fitness. The budget I have for this project is less than $1000. I'm looking for an experienced developer who can create a simple yet effective mobile app that is functional and user friendly. The app should be easy to navigate and intuitive to use. I expect that the developer will deliver a product that is well-designed and provides important features to aid the user in achieving their fitness goals. Ultimately, I look forward to a result which will provide an interactive experience that keeps users engaged and motivated.
