Classic example: Todo App
Write a to-do then add it to your list of to-dos. You can track not only the number of completed ones but also those that are still in progress. Once you are done with a to-do, check it and move to another one.
If you added a to-do but unfortunately forgot when it was created or checked, do not worry the app keep this information for you. If by mistake you deleted a to-do, you still can undo this operation.
The logic and state management of this App is implemented using Redux. Components and the App view is mainly build on material-ui.
