Journeys & Notes - This is a social based app that's made for travelers. Microsoft says:

Whether you're taking the bus to work across town, or jet-setting across the globe, checking-in to your trips with Journeys & Notes unlocks a community of people who have traveled the path you're on.

The road may be long and lonely, but we help connect you with others along the journey. Leave behind notes for your fellow travelers to discover, or stumble across the serendipitous gems of wisdom shared by others. Microsoft Garage turns fresh ideas into real projects.
