FlashWorks is a vocabulary drilling program. Each word is tagged for difficulty, type (noun, verb, etc.), chapter, and frequency in the Biblical text. You can then ask for any cross section you wish, such as "all verbs occurring more than 30 times in the New Testament that occur in chapters 16 through 24 in the text.
FlashWorks remembers words as you get them right and/or wrong and can automatically set the difficulty rating. There are databases for Greek (Basics of Biblical Greek), Hebrew (Basics of Biblical Hebrew) and other languages.
InstantTranslate makes it really easy to translate a selection of text in the application you are working in from one language to another language.
