It allows you to make lists - lists of your favourite things and lists of things to do, goals to achieve etc. For lists of 'goals', you 'tick' them off online when you've done them and it updates to say what percentage of your list you've completed. Very rewarding!
I'm 11% of the way through my 'Moving' list that I started yesterday.
I'm not giving up on the Excel spreadsheets and Word document lists just yet though.
