It used to be a great dictionary but recently it started to check if I am human every time I want to check the word. It extremely annoying, especially when the Internet connection is not the best, it takes ages - I'm also pretty sure I installed this dictionary as it was advertised as offline dictionary and somehow it become online only with this annoying check every time. I started using other apps as I'm fed up with this...

Pawle, dziękujemy za Twoją opinię. Rozumiemy, że wielokrotna weryfikacja może być uciążliwa. Nasz dział IT wprowadził poprawki, więc mamy nadzieję, że zmiana jest odczuwalna. W razie uwag napisz do nas na pomoc@etutor.pl. Dodamy, że słownik jest dostępny jedynie w wersji online.

THE best online dictionary. I always recommend it to my students because it's reliable, packed with words (even the more obscure ones) and examples. Most importantly, the definitions are correct (which is not that obvious for the creators of other online dictionaries, apparently...). The app works just fine, doesn't lag and is easy to use. It saved my sorry a** on many classes and translation exams at university ;)

So many advert banners I have to click almost every time I want to use the dictionary. Why would you do that, and why can’t this app remain simple and hassle-free!? As I said before, I’m not interested in courses, and I’m happy to pay to have this app free of this nonsense, but no – instead, they bother people in exchange for nothing. Great PR, guys – so not too smart!

Przykro nam z powodu niedogodności. Diki to darmowy słownik, więc szukamy różnych opcji finasowania, a dzięki środkom ze sprzedaży naszych kursów z platformy eTutor mamy możliwość rozwijać w dalszym ciągu obie platformy. A zbiór haseł jakim dysponujemy, to chyba jednak nie takie nic šŸ˜‰
