Since 2009, I use a FreePlane mind map to keep track of all my daily tasks, long term projects, ideas and a private knowledge base. This mind map has grown to about 500’000 nodes (individual thoughts, tasks, snippets of information) within 15 years. To open my mind map also on my Android phone, I have developed DroidPlane, a mind map viewer for Android.

To minimize the memory usage of my application, DroidPlane does not display the whole mind map at once. Instead, the application starts with only the root node of the mind map. From the root node, the user can “dig” into deeper levels of the mind map. Whenever the user opens up such sub-level in the mind map, the nodes are loaded and displayed. This way, DroidPlane does not need to layout the complete mind map, but only the currently displayed nodes.
