Installed it on my Windows Phone, working great. For a long time, I've been looking for usable maps for my Lumia, as Here Maps, which came pre-installed on my phone doesn't have support for Pakistan. And all Google services, including Google Maps, are missing from The Windows Phone Store.
The app is working as it should and seems to be WAY lighter on battery than gMaps (An unofficial client for Google Maps for Windows Phone). Location service also seems to be working more accurately, whereas gMaps would take ages to get a GPS lock under 7 Meters.
Premium features are available for 7 days as a trial but apart from turn-by-turn navigation and lane guidance, all premium features are passable, really! Besides, some premium feature like speed limit alerts, 'speed cameras' and traffic condition are not available for Pakistan as of yet, even for premium users!
Overall a brilliant app. Way superior than Google Maps in some scenarios, specially off-line navigation which is absolutely matchless!
The whole Pakistan Map with ALL POIs etc was just 116MB's in size! Whereas downloading an offline map the size of Punjab would take upto 1.5 GBs on Google Maps! You can go anywhere in Pakistan, and you're covered! It's absolutely crazy when you consider The 3D nature of the maps and the kind of detail it has to offer!
11 out of 10!!!
