Follow The Red Dots - Hierarchical Leitner Box

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.
