Trace-Me enables you to trace where you’ve been and augment that information with pictures and stories that you’ve taken on the road. It’s especially nice for holidays or any other trip. It can be used by yourself to afterwards see where you’ve been and what you’ve done, but you can also give your friends and family the opportunity to watch where you are live in real time.
