There is the simple philosophy in usuability, “If something is hard to use I just don’t use it as much.”
Well since starting to use this app I find that I am using it… alot! This iPhone app, CheckIt, from the company Thinking Code, is simple enough for “to do dumps” for quick access and yet I find it still also has the depth of some of the higher paid apps in it’s category. You can do multiple project task managements and organize things into thing needed to be dome today, week, and see which things are overdue. It seems to be as simple as you need it to be or as comprehensive (yet simple) as you need it to be.
If something is easy to use (like CheckIt) I will use it all the time…
