The most awesome and surprising thing about this is that the whole thing runs locally on your smartphone! You don't need network connection. All dictionaries, grammar processing, image processing, DNN - the whole stack runs on phone. I used this on my trip to Moscow and it was truely god send because it didn't need expensive international data plans (assuming you have connectivity!). English usage is fairly rare in Russia and it was just fun to learn Russian this way by pointing at interesting things.
