People like business men, students, drivers, and many others, enjoy using this application. The same for people who tired out after working hard all the night and need to rest.
Just define your white list numbers and activate the application. You will hear no ring for undesirable calls, but the calls from the white list.
You can also select a message from a predefined message set. "No Disturb" application will send it automatically to the callers whose calls are made silent for you.
You can switch to other applications on your phone, while "No Disturb" application is activated and taking care of its responsibilty. However, if you exit it, the service will goes down, and you receive your incoming calls normally.
