Unreliable

With the latest iphone 4s and OS, and with most frequent update selected, with good 3g connectivity, and phones turned on 24/7, this app continually spews errors "Error getting location from core location", not once, but twice for each phone. When I say "Show iphone on map" it often plops me in the Indian Ocean. Phone locations are out of date by days, if not hours. "Tracking", therefore, is highly unreliable.
