It has promises but I cannot recommend it because of the following shortcomings:
It cannot detect/recognize a language outside of the one it's currently set to...!

The pop-up option is good & it can translate both live chat & stationary pages, that is if you have it set to the correct language otherwise it's useless.

I'll be uninstalling this app too (a lot of useless to my needs apps, but between them, there's a great app to be had...)
