The application is great! The UI is clean, easy to follow. It does exactly what it is intended to do. I have one suggestion. Alongside the possibility to add steps to the tasks, it would be great to be able to arbitrarily set the level of completion of one task with something like a slider. Say for example you set yourself the goal to watch a full youtube playlist. Everyday you move this task to "My day". You will want to be able to measure your progress each day without predefined steps.
