I found a free iPad mind mapping tool by Inspiration

I use Inspiration 9 to do my mind mapping, working out problems in stories, that kind of thing. They created version 10 recently, but the upgrade does not look like it is worth it for me.
I saw on their site they were advertising a version for iPad. It’s not expensive, but that aside, it starts as a free version which you can then upgrade should you desire.
I suspect the free version will do everything that most normal users of a tool like this will desire.
They call it Inspiration Maps.
It’s not as flexible as Scapple, but it is very easy to use and works with a finger, or the Apple Pencil.
Worth a look if you find sometimes you need to look at a problem visually, as I do.
