NT Greek Resources is having a 50% off sale on the following apps (click each one for the iTunes link). Check out Brian LePort’s review of these apps (FlashGreek, ParseGreek, and iGreek). Instead of rehashing these excellent reviews I will just say I wholeheartedly agree with his recommendation. I have been using these apps for awhile now and they have been invaluable. The parsing app is especially helpful for parsing on the go and iGreek is useful for a quick reference.
FlashGreek Pro - $4.99 (regularly $9.99)
One of the great features of this app is that it includes vocabulary lists for the following grammars:
iGreek - $1.99 (regularly $3.99)
