FindMyCar application is to save the location that you parked a car.
It saves relatively accurate locations if GPS is available, and, if GPS is not available like as indoor parking lot, it saves a little inaccurate upon base station, or guides you to take a picture to find out easily the parked location.
For instance, it happens that you cant remember the parked location, long time after you parked a car in wide parking lot, like as big outdoor parking space.
In case of indoor parking lot, its useful to use " Photo menu", because GPS is not available most of the time. It will be easy to remember the parking location.
In addition, theres " Sending my location " function. For example, you can use it when you need to call tow truck in case of car accident. Just need to send the location simply, without detailed explanation. And if you are in distress while climbing mountain or you cant explain your place easily, it will be very useful for you to use this app.
