For free maybe ok, for almost €10, no. It’s a nice enough mindmap, but not really made for ipad. It can rotate the map, which is sort of interesting, not really useful if building a KnowledgeBase. Importing files is limited to images, database files, xml and wikipedia and other websites. Not local text files. Publishing files on the web before importing them is silly. The images are tiny and can not be enlarged. Seemed like it could be useful, sadly not. I’d like my money back please.
