App or Total Useless Joke?

This is a complete useless app. In a metropolitan area with full signal and it took over 40 minutes to load a 30 minute walk...and then, the tracking looked like hundreds of straight lines crisscrossing each other. Completely unrecognizable as anything.
What are the creators thinking releasing this total trash?
U S E L E S S!
