I’m surprised SimpleMind didn’t make the list. I’ve tried a quite a few mind mapping tools and SimpleMind seems to be the most consistent across platforms; it has one of the best touch UIs I’ve come across on any platform; data is pretty easy to import/export and it syncs with most cloud providers out of the box; they don’t nickel and dime you with subscriptions; and they deliver consistent upgrades and useful features.
