Orange has released the first version of its Libon app for Android smartphones and is adding new functionality to the iOS version. Libon appeared for iOS in November last year, giving Orange a clear competitor to so-called over-the-top (OTT) applications such as Skype and WhatsApp. Like T-Mobile USA’s Bobsled and Telefonica’s Tu Me, the app provided free HD calls and messaging to other users of the same platform, regardless of their carrier, as well as voicemail transcription.
