Starbucks CEO says better pricing transparency necessary for mobile app

Starbucks CEO Brian Niccol believes the company's app isn't transparent enough on pricing. He wants to fix that. 

"I don't think right now it's very transparent for people to understand when they're modifying their drink, how that modification translates into their drink price," Niccol told FOX Business digital in an exclusive interview.

One of the things the company is working on is showing customers in real time how their drink order price increases when they add extras, like an additional pump of flavor, Niccol explained.
