This thesis deals with the comparison of classic car insurance and car insurance managed via mobile application. The paper lists the advantages and disadvantages of both sides and links them to the needs of the end user. In the paper, a mobile application is conceived, designed, and created in order to make the conclusion as clear as possible. The application is being developed because it is based on telematics, a new branch of technology that uses sensors from smart devices to define output parameters. Namely, with the help of sensors, the driver's driving behavior is recorded and a rating is assigned to him. Based on the rating, the user receives benefits or increases in the next car insurance premium. This way is considered to be faster, cheaper, and more efficient than the classic extension and negotiation of car insurance in person. Regarding the application, it must be created for all operating systems available on the market (Android and iOS) and must be intuitive in order to familiarize the user with this new technology in the shortest time possible. The design of the application is a key factor in the acceptance of the application by the client because it is necessary to present the complexity of the combination of car insurance in general and telematics information technology in a visually pleasing, simple, and intuitive way. In addition to a visually satisfying display, it is necessary to implement all the technologies that deal with the recording, processing, and reproduction of telematics data so that the model for calculating the rating and price of premiums would be accurate. When testing the application, it is necessary to observe the simplicity and intuitiveness of solving actions such as extending or contracting car insurance. In this way, a realistic picture of the comparison of classic and digital car insurance is obtained.
