It is fairly good app but...
Some dictionaries like polish-english are missing basic words. This one dictionary only has 107 000 words which is not so much when compared to PONS 300 000 polish-english dict.
ALso the translaton is pretty simple ( meaning bad), there is not sentence example or much audio. It only gives you word to word translation which can be confusing at times. They should definately imporve it and take the example from PONS, which offers really rich translation.
