Windows Phone - NZ Topo Map app

Have you got a Windows Phone 8 device? I'd be keen to get some early feedback on the NZ Topo Map app I'm developing for the platform. You can grab the app here: http://www.windowsphone.com/s?appid=b861ab51-a68d-456f-9ae4-cbed66736b36 The app is a work-in-progress, but I've released it early as I'm keen to get feedback to make sure features work as expected on different devices. I also want to hear about any issues / niggles experienced so I can create something useful and easy to use. I've been taking the app offline on tramping trips myself and it seems to be performing well so far. Current functionality: • Map caching for offline use. • Show current location. • Create waypoints. • Record your tracks. Planned functionality: • Share tracks as GPX or KML files. • Share waypoints as links. • Compass. • Location search. • Map caching in background. BTW: I'm also actively improving the mobile version of http://www.topomap.co.nz which can be found at http://m.topomap.co.nz - will be adding new features such as search soon. Cheers, Gavin
