View Here : Uber Price Quote
At the time we learned that fare quotes, shareable links with trip map, and the ability to split fares would be coming to future updates. Today we get fare quotes with version 188.8.131.52 of Uber.
I have a Windows Phone and have the Uber app. It used to give me a price quote for UberX. I looked at it again last week and was notified that price quotes were not available for UberX.
