Best iOS mind mapping tool

My mind mapping needs were previously served by Mindmeister, but I had gotten frustrated by the lackluster usability on iOS. After trying out SimpleMind, I was hooked! I love the minimalist visual styles available, and its easy to positions nodes quickly and precisely. Using SimpleMind on my iPad Pro + Pencil is a brainstorming dream! Dropbox sync works great for sharing between my iPad and iPhone, and exporting to PDF and sharing to other apps via share extensions is smooth and seamless.
