Beats Todoist and 2Do and others I checked out
Does everything I need for free (unlike Todoist that wanted to charge a lot every year for these features) and it syncs with a desktop version (also free) unllike some of the other to do apps out there. Be sure to set up the function that allows you to forward emails to the app, making them into action items instantly.
