I did came across this interesting note app not quite long. This is an application with new and exquisite features. It's features are quite unique and different from other note app I have seen before.
The name of this note app is called Transno. Transno is a note application that allows you come up with organising your words by mind-mapping.
It allows you to see the mind map structure of a note when you write a headline, sub-headline and bullet items in that note. This in turn make your thoughts looks more organized and clearly written. Others get to understand it even better.
