The app takes advantage of Bluetooth Low Energy for passive gameplay.
PKPKT (read “pickpocket”) is an iOS game that feeds off of Bluetoth Low Energy (BLE) to simulate digital pickpocketing, where crime is not illegal and people can make money by stealing from nearby players. Players are given $1,000 in virtual money, and depending on their sleight of hand, that money will either increase or decrease. Whenever a crime is committed, the app will give the thief the right to boast about their mischievous action over Bluetooth.
PKPKT is one of the first games to make use of BLE in a non-commercial way. But considering its presence in the iTunes store, the current version of the app is more of a pilot than anything else. Schoenherr hopes to include new weapons and achievements in later updates.
