I don't know about app making money. however, I know about BitUniverse which's an app that helps you grid trade or "make money". and on its recent news, it integrated ProBit into BitUniverse successfully.

Grid trading allows you to place multiple buy and sell orders for a trading pair.
-When the price of the token drops, the buy orders are transacted.
-When the price of the token increases, the sell orders are transacted.
This way, a grid trader would be automatically buying low and selling high "making money."
