For the first time in a single week, more than a billion apps have been downloaded, according to a study.
Analytics firm Flurry said 1.2 billion apps were downloaded in the last week of December.
Activity was buoyed by the facts that many users received new devices for Christmas and firms offered discounted apps over the holiday period.
The US was responsible for nearly half of the downloads, followed by China and the UK.
With 81 million downloads, the UK easily surpassed Canada (41 million), Germany (40 million) and France (40 million).
It was beaten to second spot by China with 99 million downloads. The US was out ahead with 509 million.
