I’m on Snapchat. Yes, that Snapchat. Since it’s banned in South Korea, the users from South Korea should have an alternative. And, there is Snow. Snow shares similar features with Snapchat.
…it is also gaining traction in China, where the country’s 700 million users make up the world’s largest internet market. There, Snow has a major advantage: Snapchat is blocked in China.

It’s available for iOS and Android.
