It is necessary to note that this application was designed by Nelson Fabbri Gerbelli, one of the authors of the great book (App Inventor. His first Android applications - Editora Casa do Código - São Paulo Brazil - 2018). In this book some ideas, codes are presented and it is up to the reader to implement and improve them. I kept a good part of the suggestions, but with some adaptations and even making the application with instructions in English and Portuguese. Many thanks to the authors and the publisher for the excellent book. It was a great investment to buy this book. Before you question, I make it clear that the value here is symbolic, cheaper than two beers. I do not drink and dedicate my life to teaching mediated by technologies.
Having made this initial justification and the attribution of credits to those entitled, we go on to the Application descriptions:
1 - It basically works with the geographical references by satellite. You will certainly use your device's data package (internet), because when parking your car, your bicycle, motorcycle and even a starting point of a walking tour, the user will be asked if they want to record the starting point. After this authorization, the App shows your location at the exact moment. You will be able to minimize the application or not, without worrying about new accesses, as it has no ads, information storage or the like. The data remains in the cell phone's memory and is then deleted at the end or return to the starting point;

2 - When you arrive at the destination or any time you want to return, just click on (where am I? "See the video provided") and then a new address will be presented. If you want to return to the point of origin (where you parked or where you started a walk), just click on the map icon. This option will trigger google maps and consequently the address registered at your starting point. These are the only moments of access to your device's data package (internet).

3 - What is the difference of this application for the different ones with similar applicability? The great advantage is that it is not based on the use of bluetooth, does not show ads and does not perform any function in the background. Everything goes through the user's permission.

If doubts arise I will clarify immediately and with satisfaction.

I hope you like it and share it with your contacts.
