I want a model for a project and app for tracking

I'm looking for a talented professional to design a model and an app for my project. I need the model to be a combination of either a statistical model, a machine learning model, or a financial model. Additionally, I have specific features in mind that the model should have, such as working as an air refresher with a solar panel at the back. The app should be designed for both Android and iOS platforms. I'm hoping to find a creative and skilled freelancer who has the necessary expertise to help me create a successful model and app.
