Mobile Mind Mapper

m3 - Mobile Mind Mapper is a mind mapping program that runs on any device that has a web browser. It uses special technology that allows you to run it and access all of your mind maps even without a network connection.

Because m3 runs in your browser, it can be used on all platforms, including Windows, OS X, Android, iOS, and Linux.

m3 is in the early stages of development, however it can be used for viewing complicated maps created by Freemind and Freeplane, or creating your own basic maps.

  • If you have already used m3, it doesn't update to the next version until you load the page twice, due to a quirk of a technology called app cache
