Does not work
Was a long shot to download it since now (July 2020) it was not clear when it was last updated. It does not work on my iPad as it has a strange bug whereby the left keys on the keyboard do not work. Will delete again.
Fix the bug
The app quits unexpectedly. I understand it's free, but no excuse for releasing a bugged product.
Simplistic and functional
This is an excellent way to do mind mapping. The only problem I had was that it wasn't intuitive how to connect text boxes with arrows. I had to use trial and error to figure out that you have to press the button for a new text box while you have the box the arrow should come from selected.
