ID this smartphone translator app?

Last year, I saw someone hold their smartphone over some Korean hangul text and an English translation appeared on the screen. I was impressed, but my crappy iPhone 5s certainly wasn’t supported by any applications that advanced, plus there was a language barrier involved with asking for any details. I finally upgraded this month to an iPhone X, so now I’d like to know: What translator app can do what I described?

Google Lens?

The Google Translate app can do this.

Thanks, that was fast!
