Thank you for your input!
We are evaluating solutions to include direct dictionary lookups in Wokabulary. Our preference would be using macOS and iOS built in dictionary. Unfortunately there is no API for those. However, you can always use the systems look-up functionality to find translations for words directly from Wokabulary (or in fact from any other app)
It is unlikely that we will directly include Google Translate. Mostly, because we don’t want to embed Google so deeply into the app. But also, because in our experience Google Translate does not work very well for looking up individual words.
We’d rather use an open API like Wiktionary.
