Mindnode

Mind mapping is a form of brainstorming that involves making a large, colorful web to represent your ideas instead of organizing your thoughts in a linear fashion. "It allows you to go in so many different directions without being constricted and stopping what you're doing," says Longfellow. You use Mindnode by writing your goal in the middle and then creating a web of notes and comments around it, showing what you need to do in order to reach that goal. This app allows you to move your notes around, create multiple maps on one canvas, and color code different branches of your map. You can also export your Mindnode map as a text file or image. [$9.99; iOS]
