What the world is seeing about the deterioration of public safety in various cities and the increase in the rate of crimes against children makes parents constantly worry about their children when they go to school and until they return from it. To dispel these fears, the idea emerges to create an application that allows parents to know the whereabouts of their children and notify them with a message if the children exceed the area specified for them. In this application, the process of discovering the child’s precise location in a specific area is carried out by determining the latitude and longitude using the GSM radio navigation system. After that, the mobile receives all the information about the location via the GSM modem. A GSM modem has been programmed to achieve communication between the modem and the child by two methods of communication through which the child’s location is determined. Ensuring that the child’s location is known at any time and informing the person responsible for tracking him is the primary function of this system. This device connects to the child in an appropriate manner and it turns on when the child exits the designated area for him, after which a message is sent to the tracker. The device can be triggered using a short messaging system (SMS) where the user can communicate remotely to the GSM using a mobile.

Distance learning is something really familiar nowadays. In the past few years, our world has witnessed a massive revolu-tion in the world of information technology and provided simple ways to obtain information at reasonable prices. Today, sharing information is an integral part of every person's life. Devices such as phones, tablets, and smartphones have be-come the main focus of digital life. With technological progress, electronic devices go through stages of software develop-ment that allow them to perform additional, more complex tasks, and process a larger flow of information. Almost every-one between the ages of 10 and 60 owns a mobile device. So mobile apps are always up to date. Therefore, it is quite logi-cal to use the mobile application as an auxiliary element in the educational system, especially as it provides many services such as accessing the Internet, browsing the web, sending e-mails, exchanging multimedia messages and files and provid-ing instant messaging applications with audio and video. Focusing on employing technology in education and its curricula, regardless of its level, is considered very important. This work diagnoses what users prefer when using the e-learning appli-cation through a questionnaire distributed to a group of university students to collect data on their preferences regarding mobile applications for e-learning.
