MarginNote 3, all brand new e-reader to better study and digest your books
Integrating powerful tools for book annotation, mindmapping, flashcards and more, to build up your reading notes as never before.
Welcome to MarginNote. This is a highly powerful reading and study software and is applicable to Mac, iPad, and iPhone. By integrating the PDF/EPUB reader and multiple powerful study tools, MarginNote will enable learners to reorganize and connect knowledge from different aspects, then memorize and grasp it accordingly.

Whatever your profession, such as student, educator, researcher, lawyer, or life-long learner, you may annotate and take notes through MarginNote, organize notes via Mindmap and Outline, connect knowledge horizontally via Hashtag and raise memory effect via the Flashcards.

You will discover what MarginNote does is not to simply integrate these tools. Instead, it combines them deeply and skillfully, which makes it easier for users to toggle between different tools.

Fix crashing on open specific PDF;
Fix the problem of abnormal mindmap caused by merging the summary into the parent node;
Fix the display effect of dragging frame structure cards in the floating window and the problem of multiple selection of cards;

Wonderful Application

It's very useful when you have to connect a lot of textbook together. It a little bit hard to use at first, but when you understand them it will improve your more productivity. easier recall information.

The app would be perfect if there is 2 additional features:
1. sync to various cloud storage not just as iCloud.
2. audio recording, yes your app will be all-in-one, I don't have to use any other application anymore.
