I bought this app solely because of the advertised claim that it "Includes a quick paste and translate option where you can translates a selected word in other application with just one click." Upon receipt, I found nothing indicating how to use this feature (or any instructions at all). I sent an e-mail inquiry, which got the following response on this point, in its entirety: "You need to use a regular copy/paste option of your Android device." Only one problem - Amazon Fire does not support cut and paste - except for URLs (this according to customer service). Furthermore, the solution as sent to me by Ectaco customer service does not describe a "one click" method. Even if Fire did have a cut and paste option, it appears I would have had to exit the application with the Russian word, open this app, then paste the word into the word search. Another point is that Fire does not have a Cyrillic keyboard, nor was I able to find an app for one, so it is not possible even to type in a Russian word to search for it. Bottom line: $20 for a totally useless app.
