Mr. Fridge Software has updated Papapapaya, a vocabulary trainer for Mac OS X (10.5 and higher), to version 1.4. The upgrade adds iPhone syncing.
Papapapaya lets you organize and rehearse your words. It includes an intelligent quiz, a learning mode, graphic statistics, live search and import/export. It organizes your words in different memory levels instead of files and folders.
Papapapaya is available from the Mr. Fridge website (http://mr-fridge.de/software/papapapaya) and in the Mac App Store for US$20. Education discounts are available for students (20% off), as well as in form of volume discounts for schools (20%-35%).
