I am asked increasingly about concept mapping software. I have previously favoured iThoughtHD; however, while this is very intuitive it is not so good at enabling inter-label links (something only realised after a little time and intensive usage!). C-Map was recommended to me as an alternative. Though not native to the ipad, it has a greater focus on the links rather than the labels and in turn this helps the author to think about structure, more than the brain dump. It forces the user to clarify: Why is x connected to Y?
“A concept by itself does not provide meaning, but when two concepts are connected using linking words or phrases, they form a meaningful proposition”. (Villalon and Calvo 2011 p18)
C-map is downloadable for Windows and Mac and wonderfully, is free.
