when I surf with my desktop PC I use the chrome extension "Google Dictionary (by Google)". With a double click on a word I receive instantly the translation. I don't need a translation for the whole side. Often I only need the meaning of some words.
Now Im looking for the same for android. Either as an extension to chrome or as a seperate app. Something for PDFs or even my kindle app that is fast and handy would be nice as well.
I'm looking for this for so long and I would happy for your suggestions. Thank you
