It can't be easy, developing a Windows Phone sat nav app in the heavily publicized shadow of Nokia Here, but when we met the folks at CoPilot recently they were brimming with confidence. They've already counted 4.5 million downloads on Android and iOS, and today they've finally gone live for owners of WP8 devices too. The free app comes with CoPilot's own, slightly different approach to laying out navigation info and options on a small screen, plus an offline map for the country of your choice, but you'll have to scroll through directions manually. For the full works, which are only free for 14 days, you'll need to spend £17.99 (the equivalent of $28) on an in-app upgrade that brings voice guided turn-by-turn instructions, a year's worth of live traffic flow info, 3D maps and a few other features. You'll find more screenshots and a growing number of reviews over at the source link.
