Trout is a brainstorming 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.

What's New

Version 1.5.4:
