Best mind mapping software for the price. Period.
I have used SImplemind for studies, working on programming ideas as well as writing concepts. It’s an easy program to use and it constraints you (in a good way) on the ideas while keeping everything neatly organized. Also, it’s one of the few mind mapping options availble on all platforms and it supports dropbox, so it’s easy to sync across all devices. Developper response is fast and helpful. My only complaint is lack of cloud support for dropbox and icloud, but the dev informed me they are working on it.
