Language Navi is an interesting, niche app. It lets users translate foreign languages inside of the app without any additional help. It uses OCR technology to recognise such languages and then translates them for you. It works in most types of apps, including messaging apps, social media, and others. Most apps with translation (Facebook, Twitter, Google Translate) work quite well. This app shall do wonders to eliminate those language barriers that become a problem with a travel bug.
