Hey, this look great! I'd say:

Looks: 11/10

UX: 3/10

For real: you have a 5-page form to add a simple task with no date, no deadline, etc).

I think you should implement a "advanced mode" at least, that lets people add todo's quickly and later review them and add details (due date etc).

Congrats on releasing, of course! Your design looks very professional!
