Our latest Route Planner app is now available for Windows 8. You will find it in the Microsoft Windows Store at http://apps.microsoft.com/webpdp/app/route-planner-8/49d2e96a-2a74-47b1-b603-7de565f93cf0.
Now, your favorite routes and tracks can be viewed and edited on either your Windows Phone or tablet or desktop PC.
Check our Route Planner 8 page for more details on the app.
Our Windows Phone 7.5 app, Walk-Run-Bike-Drive, shares routes and tracks with Route Planner 8. Sharing between your devices is easy using SkyDrive. Also, Route Planner 8 uses Windows 8’s native sharing allowing you to email a map of your route or location to anyone.
For example, use your Windows 8 desktop PC with Route Planner 8 to set your route. Enter all your waypoints using your keyboard. Then use RP8’s Save-As app bar menu choice. Pick SkyDrive and save your route to your RoutePlannerWP folder. Then you’ll be able to open the route on your Windows Phone from SkyDrive.
Next up, a new version designed specifically for Windows Phone 8 and additional features for Route Planner 8.
Send us an email or comment if there is a feature you would like to see added.

When are you going to correct the software version of walk-run-bike-drive at the windows store? The one that says it is 1.10.3.x is not. and it will not accept plain old. gpx files.
I checked the Windows Phone store and, yes, something is wrong. Microsoft apparently is not distributing the correct version. Today, I submitted an update to version 1.10.1.4. Microsoft usually takes about a week to publish an update. I will monitor it.
