I did not know this app existed but Im so glad I found it, and its free!
Much better than other Arabic-English dictionary apps out there, and it includes short vowels (unlike google translate)
It sort of seems like the app is designed for Arabs bc there was a message in arabic at first and the buttons have arabic letters. Still: its a dictionary and needs no instructions. And it translates both ways (Ar->Eng, Eng->Ar)
Five very happy stars
