make tracking app

To create a mobile app for tracking, you will need to use a programming language that is compatible with the platform of the device you want to target (iOS or Android). You can use Java or Kotlin for Android and Swift or Objective-C for iOS.

Here is an example of how you can create a simple tracking app using Java and Android Studio:

1. Create a new project in Android Studio and select the "Empty Activity" template.

2. Add the necessary permissions to track the user's location in the AndroidManifest.xml file.

3. Use the LocationManager class to request the user's location and update it on the UI.

4. Create a new layout file for the main activity, and add a MapView to display the user's location on a map.

5. Use the FusedLocationProviderClient class to get the user's current location and update the map view with the user's location.

6. Add a button to start and stop tracking the user's location.

7. Use the Service class to run the location tracking in the background even if the app is not open.

8. Finally, test the app on an Android device and make sure that it can track the user's location accurately.

Note: This is a basic example, you can use third party services or libraries like Google Maps, Open Street Maps, and so on, to make it more functional and robust.
