Not very good
I wanted to like this app, especially since it's free, but found it disappointing.
There're no configuration options. The color scheme and fonts are fixed to a single red central idea and all nodes are blue on black background which is very limiting. All nodes and links, even the lower level ones are the same size & color which it makes it tough to differentiate.
The flexibility of adding different types of nodes is nice, but the UI is poor as it takes too many steps and isn't intuitive. And regarding UI, if a node has more than four connections, adding another overlays the new one on top of the source node.
Where are the options for synching to the cloud too?
And what's the point of releasing a mind mapping app so late and not optimizing it for the iPad?!?!?!
It's promising, just not ready for prime time.
