App for tracking mileage

I am looking for a freelancer to develop an app for tracking mileage that's compatible with both iOS and Android platforms. The app should include both GPS tracking and expense logging features. I'm looking for the freelancer to have creative freedom to design the app, with guidance from my preferred design aesthetics – I like the look of the website www.mileiq.com. The overall goal of the project is to bring this app to life in an efficient, practical, and user-friendly way. i need a login page aswell for clients
