Hi there! I'm the developer of TrakUrMiles, so I can help you out if you haven't already figured things out!
There's a toggle to switch from miles to kilometers in the settings of the application. To get to the settings, swipe down from the top of your screen while you're in TrakUrMiles and click on the "Settings" button. At the top of this page there's an option to change to kilometres. I hope that helps and that you enjoy the app!
