One use case for the what is my address tool is whenever you are visiting a friend and want to store their address in your phonebook so that you can look up their address when you want to visit them again in the future.
Sometimes, it is not obvious to know your friend's address just by looking at the house, with my address lookup tool you can find their address quickly.
You can share your current address with others for meetup purposes. For example, if you are meeting somebody at a specific location, but you are not sure what the exact address of the location is. You can then use my address tool to look it up and share it with whoever that you are meeting with.
Another use case for my address is when you are lost, and you need someone to pick you from your current location. You need to give them an address, and that's when our tool comes in handy. You can look it up to your location and give them the address with your mobile phone. As long as you have the location enabled on your phone, our tool will be able to pull your current address.
