Reachme is a Windows Phone app that offers a simple means of sharing your location with others. The app is a Microsoft Garage project and lets you send your location, along with turn-by-turn directions to get to that location. While sharing your location with Reachme is presented in simple fashion, to share your location the recipient will need a Microsoft Account, be listed in your contacts and have Reachme installed on their Windows Phone.
All of which does give Reachme a rather restrictive feel that will likely tarnish any appeal the app has to offer. The app has potential and I can see it coming in handy, but Reachme needs a option of sharing your location without the need for the recipient to have a Microsoft account and Reachme installed.
