For caffeine lovers who couldn't actually pull an all - nighter without coffee, and hate to travel to Dunkin' Donuts outlets for a cup, will definitely find Dunkin' Donuts easing their pain.

Starting from Tuesday, March 8, members of Dunkin's rewards program can begin ordering, paying for coffee, donuts, and other items via the mobile app at certain locations in Massachusetts and Rhode Island.

The "Dunkin' VIP App" is presently available only for iOS users, but they might soon be launched for non-iPhone users.

"We've been really pleased with what we're seeing," Scott Hudler, Dunkin's vice president of global consumer engagement, said of the Portland-area test, which includes some New Hampshire and southern Maine stores, according to The Boston Herald. "Usage continues to rise. We want to extend it to Boston - our hometown - and get greater and more robust consumer data."

Dunkin' rolled out a pilot program in 124 locations in Portland, Maine last November, not long after Starbucks launched its own mobile ordering system, as the Verge reported. 

Notably, the announcement of Dunkin' Donuts comes just after Starbucks announced that they have partnered with delivery app Postmates to deliver the beverages to their clients doorsteps.

Dunkin' Donuts has also launched deliver in Dallas, after collaborating with DoorDash, with eventual plans to expand to other cities, according to Eater.

Meanwhile, the extension of the Boston market will reportedly allow Dunkin' to further test the app and order fulfillment before a planned national rollout later this year.

"We're going to learn a lot and make adjustments," Hudler said. "We will make sure when we're ready to go that we have fully pressure-tested this product. Once we roll this out nationally, we will have one single app that will have all the functionalities we have today (in the regular Dunkin' app) plus on-the-go ordering."
