Now you may be thinking, “Everyone already uses Google Translate. It’s what got me through my Spanish class!” But did you use the app to its fullest?

The Google Translate app has many different features that enable the user to translate languages with efficiency. There are more ways to translate a sentence than having to type all the words in yourself and dealing with an auto-correct that keeps changing "me llamo"into "me llama". With Google Translate, you can simply look at the foreign words through your device’s camera and see them translated before your very eyes. Also, you can handwrite the language you're seeing for quicker and easier input without any hassle. If you already knew all that, did you know that the app also has an offline mode for easy translating virtually anywhere?

4. Line

Line is a Korean free messaging app. Users can create a personalized profile that friends can comment on with a picture, video or text message. The app allows you to create group chats, follow celebrities and even talk with friends anytime you want with free calling – not to mention the hilarious stickers it comes with to liven up any chat. But the thing that sets Line apart from other popular messaging apps or your own phone's SMS is the app's ability to translate your text live, enabling you to text someone who does not speak your language. That’s right, no more language barriers!
