The Twilio Developer Contest is an ongoing competition where developers can submit their apps built on the Kynetx platform, a unique platform for building apps that can interface with users on any URL or web-enabled device. The contest aims to encourage developers from all backgrounds to try Twilio for different use cases, industries, and integrations. To participate, developers can submit their apps by November 7th, at 11:59pm Pacific Time, and can receive a 16GB Wifi iPad and $100 in Twilio credit as a prize. The contest is open to anyone who has previously submitted an app but didn't win, allowing them to resubmit with improved versions of their work.
