Hi, my name is Dragan Milicevic.
I have developed a todo app with integrated financial planning.
https://machwas.herokuapp.com/
There you can find a description of the app and a demo link.
The application is still in beta phase, so feedbacks are welcome.
Within a weekly view you can plan todos as well as income and expenses.
The demo runs completely in the browser, as a JavaScript application without server communication and without server-side data storage.
This means that the application is fully functional, with additional features expected in the near future :)
