I usually take a pen and write it on my hand or text it to myself. I just thought it was weird how one day the Find my Car Lite app showed me the floor from what I saw and then I never could get back to that same screen. It always showed me the map after that. But I saw a white checkered screen with an arrow on the 5th line. But I'm gonna try it again I just didn't know if there was a better app or not.
