Phone Locator for Free GPS Phone Tracker is a free application that lets you find your family or friends in a matter of seconds. If you have a previous code and have given your consent to be located, then the application will be able to find your phone. The best thing is that it does not need any special permissions to work. 

Once the application is installed, you can select the person you want to locate and then choose to track them by giving them the code that will appear on your screen. 

If the person does not have the application, then you will be able to see their location in real-time. You will have to wait for the battery to charge.
