If you frequently forget where you parked your car, Auto Finder for Android could be what you’re looking for.
Though there are other apps out there that let you pin your position to a map when you leave your car, and there’s other Bluetooth-enabled solutions too, Auto Finder automatically marks your location when it detects that your car has parked using your device’s built-in hardware – zero configuration is required. Though it does require Android 4.0 and above.
You can operate in satellite or map mode, and you are also able to manually mark a location if you wish. It also serves up directions back to your parking spot. The icing on the cake? This is completely free to use – though if you like it, you are encouraged to support development with a donation.
Agent for Android offers similar functionality, but its focus falls way beyond that of simply parking.
