@ilsonfan There are no plans for an update as of now but things can always changeWe were pretty surprised when the official Waze app for Windows Phone hit the store in November last year, expecting Google’s purchase of the crowd-sourced mapping and navigation app in June 2013 to put an end to development.

It seems in the end it was merely a temporary reprieve, as a 9th July tweet from their customer support on Twitter has confirmed the company has no plans for any further updates to the app. That app was last updated on the 25/2/2014.
The app as likely a victim of Google’s animosity towards Windows Phone, as otherwise it seems rather interesting that a small company like the pre-purchase Waze could find the resources to support Windows Phone while a giant like Google can not.
