You are standing in a traffic jam, in a railway track, at customs, etc. Run this application and you can pokimarite until the car in front of you will not go, and the program will notify you with a sound signal.

The application does not work in the background, its principle of operation is related to the processing of the image on the smartphone screen, i.e. the smartphone must continuously display the image from the camera on the screen. The function is programmatically enabled so that the screen does not go into hibernation. Every new version of Android puts a lot of emphasis on security, and the latest versions prohibit the use of the smartphone's camera in the background.

You can use an old smartphone with a broken screen, attach it to the dashboard in the car and plug it into the cigarette lighter so that it does not run out of battery and you will be happy!
