This judicious application -for no it is not an e-book-in its design, is to install on the kindle or on anywhere tablet Android and farewell the faults! For the price it is absolutely brilliant and this app works in a closed circuit. Namely that there is no need to be connected to the dictionary. For young people (and others too) is an indispensable tool. For the price it would be a shame to miss and unlike his brother paper, he weighs nothing! I highly recommend this great application ... Larousse is the big brother to everyone! (Approximately 20 good minutes for installation on the last generation Kindle Fire).
