Windows Phone app wanted

[#1]

Been looking at apps, on the Google Play ... can see many phone finder type apps for android... does anyone have a free one for Windows Phone  ? Preferably one that can be a phone tracker too... i.e. if lost or stolen, it can report back it`s location.  (not just one that beeps, when it is under the sofa ! ! )
thanks
