The mobile device industry allows developers and designers to incorporate different sensors, processors and memories into electronic devices that are of different dimensions and shapes according to the purpose for which they are intended and for which they will be used. Additional sensors are used to improve the usability of these devices and the quality of the experience by data collection and analysis. There are various mobile applications that communicate with sensors, thus expanding and enriching the functionalities that mobile devices can contain. In this final paper, mobile devices are considered from the point of view of functionality, dimensions, architecture and other aspects that make up a mobile device. The most commonly used sensors in mobile devices are presented and explained, and each of them is further explained in the way they work and for what purpose they are most often used. Various development environments for the development of mobile applications are listed, such as: Android studio, Cordova, MIT App Inventor (MAI) and others. It also describes in detail the mobile application that fulfills its functionality using various mobile sensors, and was created with the help of the development environment for the development of the mobile application MAI.
