This paper presents the creation of a web application that helps with learning and manages tasks, where technologies such as CSS, HTML and JavaScript were used. It is also important to note that the entire application was created in the Visual Studio Code environment. This app is based on the Pomodoro technique, which is one of the most proven effective learning techniques today. The Pomodoro technique is known for having cycles that last in intervals, where the first cycle lasts 25 minutes, followed by a short break of 5 minutes and so three times, after that, there is a cycle of 25 minutes, which is also known as the pomodoro cycle, and then a longer break of 15 minutes and so on and on. That is, after every 4th cycle there is a longer break of 15 minutes. The application is made to be useful and to allow users to concentrate on their tasks as much as possible. Also, in the application, the entire list can be seen in the Mind Map, but also in the 3D Mind Map, if the user wishes. The application contains various functionalities, and some of them are: adjusting the counter according to the user's wishes, saving and reading tasks, adding categories, E-Ink, etc. The application is expected to significantly improve the concentration and overall academic performance of all students who will use this application, but this application can be used by everyone, not only students and students. Through detailed explanations of functionality and examples, this paper serves to understand the development of such a web application and the application of technology to improve the learning process.
