Grinder currently has around 15 million active users but only around 1.1 million are paying. Currently the app has limited the functionality for the remaining 14 million users. But if you go to pay for the app, the prices are extremely high compared to other apps that you Pay for. I would recommend lowering your prices for all users at a six dollar weekly rate to draw the remaining for users into a month-to-month or week to week contract.
