Team Wizard app for iPhone and iPad

The purpose of the application is the tracking of the movement of people in the group. The application uses all methods of communication with backend server (GPRS, EDGE, 3G, Wi-Fi). For example, my friends and I had lost when we went canoeing. It was disaster and we spent a lot of time to find our group. It will never happen with you if you install this application. It allows you to follow your team and to call for help if anything happens. It can be helpful for any other groups: excursion groups, group of players on the ground, parents and their children etc.
Each team has protection code and info about its movement available only for members of the team. This info isnt used *anywhere* except this application.
Every master of the team can share info about its route in social networks, but it cant publish info about members of the team. And only members of the team know the list of the group.

Continued use of GPS running in the background can dramatically decrease battery life.
