Todoist is the cornerstone of my organizational system. I am an undergraduate student and use this app to manage my reading assignments, exam schedule, administrative deadlines etc. sync with windows 10 desktop app is awesome. I am a free user and would gladly pay a one time price for full features here but a monthly subscription is a turn off. most recent update added check boxes which confused and altered the functionality of the widget (which was wicked BTW!). please add ability to turn off.
