WordLens uses text recognition to work out what the word or phrase is, and then automatic translation software translates it into the new language.
The translation is then pasted over the original location, practically in real time.
The app has been available on the iPhone with Spanish translation for about 18 months, but is now available on both major smartphone platforms with the new range of languages.
A promotional video for the app which shows it instantly translating a number of signs in both languages has already become an internet hit, the newspaper said.
The app is available for around 3 pounds.
