You may have heard of it recently, it has been dominating headlines over the last 24 hours for two reasons. Firstly, its simplicity. The app allows you to message friends with the word ?Yo? and that?s it. Nothing else can be said other than sending this innocuous greeting.
The founder Or Abel told the Financial Times that he coded the app in eight hours, after being asked by his then boss Moshe Hogeg, to make a notification app that could summon his secretary. After testing the app on colleagues who apparently loved it, Abel then moved to San Francisco to pursue the Yo app venture full-time.
