Our client, Swim Across America, unites the swimming community by hosting benefit swims that raise money to fund life saving cancer research and clinical trials. They came to us with a new feature request to address an important safety issue they have on the day of their peer-to-peer events. Swim Across America needed the ability to identify when a swimmer has left the water. They needed to be able to see if everyone made it out of the water safely and in turn know how many individuals (if any) are still in the water.
