I like to keep track of all things: shopping list, payments, projects, appointments and so on. In doing so I know when I'm way behind as there is a pile of items in "pending". So I use Trello (most tasks, projects) integrated with Calendar (appointments, due dates) and Google Sheets (all payments, due dates).
