If you keep forgetting where you park your car, this application is worth checking. The Find My Parked Car is a free android application that saves your exact parking location so you can locate it quickly when needed. With the app, you can detect the location of the parking spot without interacting with anything and even receive walking directions as you walk back. This app is handy for people with a poor sense of direction and who always get lost in the parking lot. 
The simple user interface also adds convenience. It has an automatic parking detection feature using Bluetooth or device sensors. You can also set it up to take a picture of the parking location, set the alarm for metered parking, and customize the theme.
