The official Yo app has finally made its appearance on Windows Phone, after debuting on Android and iOS recently. The app is very simple and all you have to do is tap "yo" to communicate with those you care about. We're not sure if they will appreciate you saying "Yo" to them, but you never know.
"The simplest and most efficient communication tool in the world. Yo is a single-tap zero character communication tool. Yo is everything and anything, it all depends on you, the recipient and the time of the Yo," the app description reads.
You can snag the app via the download link below. It's free. We're not sure how long "Yo" will remain popular but give it a try if you are daring and let us know if you like it.
