Really nice clean UI and smooth UX, not laggy at all. You can divide tasks in groups and sub groups, and attach a due date to it and tell you when the task is overdue. The second best thing about this app is the "plan" app feature. The feature shows what task you have planned for the day and shows you the task one by one and lets you pick when to do it. Very nice feature but how many times you can plan your tasks is limited in the free version. I wish there's an integrated "Habit App"feature
