Organize the notes automatically in the categories TODAY, TOMORROW, LATER, and SOME DAY. Each category can be retracted and redeployed when desired. Each note can have the details we want and alarms can be generated so that the app warns us of the important things we have to do. The tasks that we are leaving undone adopt different shades of red according to the amount of time that has passed, while the tasks for which we still have time appear in a pleasant green tone. All this is designed with simplicity and elegance, so that the user does not have to think more than what is important. In addition, this app has the advantage that your notes are stored in the device occupying very little space. If you distrust to give your data to the cloud, this is your application of notes.
