It's a really complete application, with several templates, responsive and well designed UI, different importing options (Ex: XMind, FreeMind). It's posible to divide a big idea into multiple sheets and it`s really useful. Brainstorm feature is great too... it`s a breeze to fill up any mapping with tons of ideas and topics. The slideshow is another great tool to present diagrams in the best possible way, with automatic or manual slide generation.
Lots of layouts and cliparts are also great enhancements to any diagram.
Besides, I've used the Android version on my Samsung Tablet and it was a nice experience, no concerns so far. Review collected by and hosted on G2.com.
