Howdyhoo! I don't recall ever seing any thread about software made for aiding classical language learners, and I have some (MacOS X) programs I've found I'd like to share (and I hope others know of more!).
Windows:
GNU/Linux:
Collatinus
KLatin
Aspell has a (albeit crappy!) spellchecker for Latin (it underlines almost every word in the Æneid as errors...)
Mac OSX:
Collatinus parses a text and generates a wordlist.
Verba is a small program for searching Lewis and Short locally.
Withaker's WORDS, fully ported to Cocoa, for those who does not like the CLI.
Andromeda, a Diogenes-ish program with a prettier interface.
Apple iOS
Lexidum Latin, an app with the Lewis and Short dictionary and a roman-to-arabic numeral converter with a pretty interface.
Lexiphanes Greek, an app with the Liddell-Scott-Jones Greek-English Lexicon and Autenrieth's Homeric Lexicon, and also a greek-to-arabic numeral converter.
Webb apps:
Poëta ex machinâ parses latin poetry, and can read it aloud.
Neo Dictionaries parses a latin text and generates an interlinear reader, based on Whittaker's WORDS.
Perseus Hopper, explanation unnecessary.
