I have tried just about every mind mapping program on the iPhone, and the only one I have found that is acceptable is #iMindMap. But the program really only works well if you are using an #iPhone6 (plus model is far better than the regular 6). This is in contrast to the high level of performance of this program and others on the iPad and notebook computers.
[The reason I find the issue of using mind maps in an effective way on a smartphone screen is that the combination of mind maps and keeping them on a smart phone in your pocket may be much more effective than having a bunch of to-do lists or even mind maps on scraps of paper in your pocket which will either immediately be lost or not survive the washing machine. As memory tools, mind maps may be particularly effective for those with various types of cognitive impairment including early or medium stage dementia.]
Here is an alternate approach. It is faster than using #iMindMap, albeit a little more “idiosyncratic.”
It strikes me that the size of the screen — the limiting factor in iMindMap (or any other phone or phablet) mind mapping — is really a limit in drawing the map (maintaining the overall map on the screen rather than only being able to see part of the map at one time and losing the context when drawing it) rather than viewing-reading the map. For reading, you can always use your thumb and forefinger and change the size through zooming in and out. This is not practical in drawing-writing the map. And of course, paper and something to make marks on it is always available. And, if I photograph the map into the iPhone’s memory, I will probably even find it again or even post it on a web site.
Whooo-hooo. There may still be a use for pencils.
[Ok, I know the next question is “why not just develop the maps on a notebook computer or iPad and then email them to your smartphone?” That is a good idea if the maps are relatively small, they are being developed for the iPad or a notebook computer as well, or you need to send copies to many people. The solution here is more oriented to simple maps for yourself or a few others such as shopping lists, driving directions, lists of birthdays and other personal facts about friends-family, thoughts on the restaurant last night, doctor appointment, medication schedules, and upcoming televised basketball games. I make such simple maps continuously and lose half of them even before the washing machine gets its quota. These small maps are notes and journal entries and to-do lists and memories, each on fairly circumscribed topics. The information needs to be recorded immediately by those with cognitive impairment so it is not lost forever.]
