Trout (Mind Mapping)

Trout is a brain storming utility which is loosely based on the mind mapping concept that allows you to rapidly associate ideas and help you organise your ideas in a non-linear way.

It could assist you with organising an event or solving a problem.
You are not restricted from cross linking your nodes and links may be labelled.
Your ideas can be categorised with color and icons and you can use images from your own Photo library to assist.
You can also work with your mind maps on the iPad version.
You can import and export Freemind format and export Graphviz format.
