Parents with overly troublesome kids. Take note. Core Principle of Indianapolis has developed an app that alerts parents when their children do not show up in class. Jeff Whorley , The founder of the app says the aim is to help boost class attendance and improve grades.

Class120 leverages on GPS and WiFi technologies to map out the campus’s layout, while allowing the student to enter the class information as well. If the student does not show up at the location where the class should have been held, a message is sent to the parent with this type of description: “Hi Joseph Montgomery, Class120 was unable to detect Amy Montgomery at the following class today: Biology101.”

Worley says an estimated number of 5,000 users will be using the app across the country by next fall.
