We’ve seen very little competition for iOS and Android, but open-source mobile platform, Tinzen may be one to watch out for. The Samsung and Intel backed operating system is launching an app competition with $4 million at stake to encourage developers to create compelling apps on the platform. Apps have proven to be a big selling point for consumers and device manufacturers so this could kickstart innovation for Tinzen, particularly with Samsung’s blessing. Also interesting is their decision to target the massive Chinese and South Korean markets, but with such a strong foothold from iOS and Android, Tinzen certainly has the deck stacked against them.
