We're travelling to Costa Rica in September and I'm looking for a really good Translator App for my DX. Something that has "conversation mode" whereby I speak, it translates for the other person & they speak back to me & it translates. I currently have a FREE app that does this very well, but requires Internet access (Google Translate engine). I wouldn't mind paying a few $$ for such an APP but don't want to pay & get sucked into a lousy APP. (and the new "policy" that only allows like 15 mins. of use sucks.) Have any of you bought such an APP that you really like? thanks in advance.
