In spite of their overbearing government, the people of Iran remain culturally liberal. And now a new app named Gershad aims to help young Iranians avoid Ershad, the country's infamous "morality police."

Ershad agents are tasked with ensuring Iranians follow strict rules on clothing and conduct. Part of this includes setting up checkpoints around town and randomly inspecting vehicles driving by. Should someone be found violating regulations, they could be warned, prosecuted or forced to write a letter of repentance saying they will never break the rules again. These checkpoints typically consist of a van with a few agents, and can move around town at will. Gershad wants to help people avoid them.
