What does it do is, you’ll search for your deceased loved ones and it will give you a search result, base on that, you will filter out w/c is more familiar to you then the app will generate the 2d grid map ( not Google map ) and will trace the path from where you at and the tomb you’re looking for. It’s great advantage is, you will not be needing an internet connection while using this. Just download all the necessary files(w/c is automatically once you start the app) and you’re done. It is pretty simple app and easy to use. It is designed to use for a certain cemetery only.
