The interface is great because it anticipates the word as you type and if your French spelling is weak - like mine is - it saves a lot of time." -User review Follow us on Twitter and become a fan on Facebook for app news, language learning tips, and more: http://www.twitter.com/ultralingua http://on.fb.me/ifI8Hy
