App: FTRD - Hierarchical Leitner Box
Developer: Catalystwo Limited
Genres: Productivity, Business

Our Hand Computer app is great way to memorize things. However, if you need to memorise hierarchical or ordered things, a flash card system is not so appropriate because it ignores the order of the cards. We made "Follow The Red Dots" (FTRD) for ourselves but it may be suitable for you too. 
Whether studying a language, vocabulary, mathematics, science or any other subject, FTRD is a great and useful aid to any student. 
FTRD is great for training your memory, and fun too.

This Mac app is the early implementation for the editor app for FTRD for iPhone.  FTRD document files (csv) can be edited by any text editor. However, using this FTRD editor for Mac makes it easier to edit.  To transfer files between iPhone and Mac, please use Dropbox.  iCloud sync may be implemented in the future.
