Perhaps it's all the "Star Wars" and "Frozen" fans.

Close to a million new subscribers a day are signing up for Disney's (DIS) - Get Report newly launched digital streaming service, Disney+, less than two weeks after its initial rollout.

According to data from research firm Apptopia, the $6.99-a-month streaming service's mobile app has been downloaded 15.5 million times, with people actually paying to use the service as opposed to simply strap-hanging on for a free initial ride.

The new streaming platform - which features content from Disney as well as Disney-owned properties like Marvel and the Star Wars franchise - pulled in $5 million through in-app purchases in its first 13 days, according to Apptopia.

Subscribers can also pay for the service through the Disney+ website, however, and that data was not captured by Apptopia.

Despite some initial post-launch glitches, Disney+ has been an out-of-the-gate force on the streaming content scene, with some 10 million subscribers joining the service since its Nov. 12 launch.

By comparison, Netflix (NFLX) - Get Report currently has 60 million paid subscribers in the U.S. and close to 100 million internationally.

In terms of who is actually watching the service, Apptopia said that Disney+ has been averaging 25.6 million sessions per day over the past week.

"Given we have seen 15.5 million downloads over the course of two weeks, this is a sign people are highly engaged with the mobile app," the research company said in a statement. "It is likely viewers are watching bits and clips on their daily commutes and briefly checking to see if new content/episodes have been added.

They're also watching via other streaming services and their corresponding apps, including Hulu and ESPN+, of which Disney+ is now part of a bigger content package, Apptopia said.

Shares of Disney have been trading near record highs since the debut of Disney+. In trading on Tuesday, the stock was up 2.17% to $152.94.
