We don’t understand exactly what European big-hitter Telefónica is set to gain from its new app. Free VoIP calls and messaging doesn’t sound like a massive money-spinner for a company that steers several of Europe’s biggest mobile carriers, but that’s what its new app is offering. Tu Me can connect through either WiFi or your own phone signal and throws in some location-sharing features for good measure. The app still will still find it tough to break through on the iPhone, which already has plenty of options, include VoIP champ Skype and the home-grown iMessage. According to The Verge, an Android version is already in the pipeline, but if you’re driving an iPhone, you can grab the free download from the App Store now.
