A new streaming video service launched today called Whatifi, that's exclusively for mobile devices and offers only interactive (choose-your-own-adventure) content. It's currently available only for iOS, for free. The content is in vertical format. At various points, viewers can make a choice between two options by swiping up or down, to send the story in one of two directions. There's also a watch party mode, where friends can watch and vote together. The app includes a messaging feature and helps you keep track of all the different endings. The service is launching with two shows, each of which takes 10-15 minutes to watch, but can easily be re-watched with different choices, for up to 30 hours of total content. The company has $10 million in funding, and is currently soliciting scripts for new interactive content with a contest offering $35,000 for winning scripts. Asked about the Android platform, a company rep said "We don't have anything to share on an Android version at this time."
