　　I'm a strong believer that learning different languages makes you look incredibly good when you're in a foreign country and can understand and speak the language. The list below is 4 apps that will help you learn a foreign language! You can download them for free.

Babbel - Learn Languages

　　Babbel is an excellent language tool to help you progress step by step with learning a new language. It helps you learn grammar along the way as you work your way through the tasks and assignments. You need to pay a monthly subscription(定金), but this will still be cheaper than taking physical lessons with a tutor!

Duolingo: Learn Languages Free

　　The app has many languages to choose from and will work through the basics all the way to advanced words and sentences. It's all completely free too! It's incredibly well designed, looks great and will help you learn, remember and progress with just a little bit of time every day.

Tandem: Language Exchange

　　Rather than have you work through tasks and memorize different things, the app lets you match with people who share your interests but speak the language you want to learn. You can then have text, voice and video conversations with people who want to learn your native language, and in return you learn theirs, all by simply communicating with each other. It's a great way to learn with only $1 a day.

Learn English - busuu
