AppTripper Travel Guide is a rather unique travel guide for our Windows Phones that covers a small collection of European cities. What makes the app unique is that it recommends travel sites based on your mood.
If you happen to wake up in Napoli a little melancholy, AppTripper will suggest places to visit that will match how you feel. As your day progresses and your mood changes, you can always adjust your destinations accordingly.
AppTripper Travel Guide is normally $2.99 in the Windows Phone Store but through the myAppFree campaign, you can pick the app up for free.
