I was excited to see an app purporting to be the 1924 Edition of Liddell & Scott's, for only 1.95. The app, however, is not named Liddel and Scott but merely "Greek-English Lexicon". When I opened it, I got a blank screen. When I clicked in the search box I got a crude Greek keyboard. I then entered a Greek word and received a message against a blank background, "No results". This app is a scam and I will be contacting Apple to void the purchase.
Should have listened to some of the reviews. Installed and came to a blank screen with no option but to type in Greek letters. Could not get any other screens no other options no other lookout. Unless you know how to type in Greek letters this is worthless. No way to look at Bible verses and find cross reference to the word. Not sure if it's a compatibility problem as some people have actually got information but I am very frustrated to find I spent $1.99 for no reason at all. Although apparently this cost more before. They must've dropped the price as reviews came in.
Great app, however.....
This is a "Classic Greek" lexicon and not a "Koine Greek" lexicon. This is important for seminary students who use the Gk. NA27 edition of the New Testament. Most of NT was written in Koine Gk. However, I can't believe it's only .99cents for the wealth of info.
With Family Sharing set up, up to six family members can use this app.
