A step-tracking app that claimed to reward its users for going that extra mile has been removed from Chinese app stores and is under investigation for alleged fraud, state broadcaster China National Radio reported Monday.

Qubu — or “interesting step” in Chinese — purports to allow users to trade in their steps for products or monetary rewards, similar to redeeming airline miles. However, to join Qubu users must provide a number of personal details, including government ID numbers and bank account information, as well as a special invitation code. The app’s developers host talks across the country, encouraging users to invite new members into the community so they can become “future shareholders” in the company, according to domestic media reports.

The app’s Hunan-based developer is currently being investigated by authorities in Changsha, the capital of the central province. In June of last year, a clever gadget that helped couch potatoes artificially inflate their step counts and brag about it on WeChat became briefly popular, despite a spokesperson for the messaging app expressing distaste for the dishonest device.
