It is an easy-to-use application, which can help you to mark a parking location of your car on a map in one of following two ways: 1. Automatically, using Bluetooth connection to your car. You don't have to do anything, parking location will be stored by the app in background. Once you turn off your car and your phone disconnects from a car, parking location will be automatically determined and stored by the application. Note: to be able to use this option, you need to choose a Bluetooth device of your car from a list of paired Bluetooth devices in the application first (this should be done only once per car); 2. Manually, using a button within the application. When you press 'Park Car', current location will be stored by the application. Pressing 'Clear' will remove parking location instead. Application doesn't drain your battery, you don't have it to be opened to operate in auto mode. It just triggers for a short period of time in background to get and store a location. Once finished, you'll get a notification on your phone.
