Beats Ironman.com
I got this app because I wanted to track more than one person at a time. Ironman.com makes you keep putting in different athletes info each time you want to track their progress- this app allows you to find them once, add them to your list, then watch multiple athletes simultaneously and keep the data handy with one click after the race is done. I also easily tracked friends at Louisville, Chattanooga, Kona, and Wisconsin. Very good app for an IM spectator and if IM would issue real time trackers on everyone and post that info, Im sure this app would make that data more useful too... Ill keep dreaming.
