Google Translate is one of those apps that has been around for years, and which therefore everyone mostly ignores. But Google is constantly improving it — on the backend, with the artificial intelligence — where it really counts.
Their visual translation feature, which used to be another app called Word Lens, is still miraculous. (Google bought it years ago and integrated it into Google Translate.) I love how it translates printed words while retaining their contextual place in your visual field. - Mike
