Mobile was a bright spot in Q4 for mobile and online payments company PayPal Holdings Inc. as well as mobile and web marketplace eBay Inc.—two companies that split in mid-2015.

PayPal processed $20 billion in mobile payment volume in Q4, up 45% year over year, PayPal said Wednesday when it reported quarterly and full-year results. Mobile payments accounted for 25% of total payment volume in Q4.

Mobile growth outpaced total growth for PayPal in the quarter. PayPal revenue increased 16.9% to $2.56 billion in the fourth quarter from $2.19 billion in the year-ago period.

PayPal’s also said its mobile peer-to-peer payment app Venmo processed $2.5 billion in total payment volume in the fourth quarter, a 174% year-over-year increase.

PayPal also is growing its OneTouch mobile payments feature, introduced in September 2014, which lets a consumer with a PayPal account that is linked to her mobile device complete a purchase on that device with just one touch. More than 15 million users have opted in to use PayPal OneTouch in the past six months, a 115% increase from 7 million announced in the company’s third quarter earnings call, Colin Sebastian, an e-commerce analyst at investment firm Robert W. Baird & Co Sebastian said in a note to investors. PayPal plans to roll out OneTouch to 100 new countries in the next six months, Sebastian says.

“As money becomes digital and the world goes mobile, we see tremendous opportunity ahead to expand our leadership, transform the way people move and manage their money and deliver increased value to shareholders,” CEO and president Dan Schulman said.

Mobile was also a strong point in eBay’s more mixed Q4 results. The value of purchases from smartphones and tablets grew 21% in Q4 year over year for eBay. “We’re aggressively iterating it (mobile) to enhance the user experience and to drive adoption and usage, and our new platform is enabling us to get new releases in front of our users more rapidly and efficiently than we have in the past,” Devin Wenig, eBay’s president and CEO said on the earnings call with investors

The mobile growth is a contrast to total gross value of goods sold on eBay’s marketplaces worldwide, which fell 1.0% to $20.68 billion in the fourth quarter that ended Dec. 31 compared with $20.88 billion in the same period a year ago, the online marketplace reported Wednesday. Excluding the impact of the strong dollar, global sales increased 1%.

In the United States, where the strong dollar does not muddy growth figures, the gross value of merchandise sold on eBay marketplaces grew 3.6% to $8.895 billion in Q4 from $8.584 billion in the same quarter a year ago.
