LocationMinder is free on Marketplace

LocationMinder will remember when and where you need to do your stuff. Simply use the search feature, or use the map to pin point a location, and specify a radius at which you want your phone to remind you, and you will never be angry at yourself again! This app has been made free very recently so that audience reach will be more. To download and experience this app, scan the QR code with your windows phone and enjoy this free app.
