Zone One

An app for measuring time, distance, and elevation change. Your route is recorded, but a scrambling feature lets you share it without revealing your location by displaying it as a circle at the South Pole. The map is black, and coordinates are not shown on screen. Perfect for people on sensitive assignments who need to stay fit while keeping their whereabouts private, such as bodyguards, special operations units, or even husbands or wives who aren’t where they’re supposed to be. It includes a built-in “weightlifting clock” with dots marking the seconds. Customize the intervals to suit your needs—perhaps for preparing your MREs.
