All new re-designed word lists now allow for more terms in Business, Financial, Oil, Law, Medical, Telecommunications, and Computers. Bi-directional functionality allows users to type in English or Russian using the bilingual keyboard with instant reverse translations available at a push of a button.

Everything from ordering food with friends or asking for directions can now be said for you! In this section, 14000 of the most commonly used phrases are at your fingertips. Just click the “Say” button and it will be pronounced instantly. You can even listen, memorize, and try it yourself to work on your own pronunciation.

Interface and Functionality

With a brand new look, every menu is now available in English and Russian. Typing in both languages is made even more accessible with the bilingual keyboard. The fine screen allows users to set brightness levels as high or low as necessary depending on preference. Volume controls are easily located on the side of the device from exceptionally high to completely off and everything in between, headphones can also be used for privacy.
