its good for watching videos as it gives line by line subtitling, and the translation suggestions seem to always be context appropriate. But I cant figure out how to export my saved words for review. Clicking the word in the list just prompts me to open the video, when I just want to see at a glance what the meaning it. Trying to export them brings up a list of irrelevant share options like twitter and discord (none of which work), with no option to just save them as a file of some kind.

I thought this is a good app. You can find articles in whatever language you are learning, and can even listen while you read which is super helpful. And although it is ad supported, they are fairly restrained, much more so than other free apps.

amazing app. One question, what type of files does the "add books" support? I figured it out that .epub is one of them, is there anything else?
