It could be better. It should be better

Good application. It helps in common life. As for me, it has to have 3 possibilities
1. repeat tasks in selected days of week. For example - Monday to Friday
2. Do not notify about finished tasks
3. If you open subtask not from the task (f.e. From today filter ) in the subtask should be button to open the task
