Yo was a social mobile application for iOS, Android, and formerly also Windows Phone. Initially, the application's only function was to send the user's friends the word "yo" as a text and audio notification, but it has since been updated to enable users to attach links and location to their "Yo"s.
History
Yo was created by Israeli developer Or Arbel in eight hours at the request of Moshe Hogeg, CEO of Mobli, who asked Arbel to design a single-button app to send a notification to his assistant or wife. It was launched on April Fools' Day 2014 for Android and iOS, though initially rejected by Apple for being too simple. The app was only shared with Mobli employees to start, however 20,000 people were using the app within the first month of release. The app was shared on the Product Hunt website, through which it exploded in popularity. Following a wide range of interest from investors, the app received USD$1 million in investment, including from Hogeg himself.In July 2014 the app was also released for Windows Phone. The app was valued at between $5 and $10 million in the same month and received a further $1.5 million...
