Yahoo Livetext app for Android combines video with written text
The app uses your Wi-Fi or cell connection and is a whole new way to communicate quickly with another person. Livetext is not made for group conversations. Consider it a way to really communicate one-on-one with a particular person.
Yahoo originally had a soft-launch of the app in Hong Kong, Taiwan, and Ireland. Livetext is now available in the US, UK, Canada, Germany, and France. All you need to do is click on the sourcelink to install it on your phone. And if you want a quick look at the app before you download it, we have a quick 12 second video produced by Yahoo to show you how Livetext works. By the way, the app is a free download from the Google Play Store.
