Good, but a couple of suggestions to make it even better
I like the simple presentation of the translations - not too much real state taken up. Im using the paid Spanish dictionary to help with my learning of Spanish.
Hwever, the app would benefit from having forward and backward buttons in the toolbar, which would encourage exploration of alternate definitions, etc. Also the ability to double click a word in the definition, and have the program take us to that entry. Finally, verb conjugations (in Spanish) should show the present and past participle forms.
