(NEW YORK) -- It's a good day to go app shopping. A number of the most popular paid iPhone and iPad apps are now available for free, in what is expected to be a promotional offering before the fifth anniversary of Apple's App Store. Wednesday will be five years since the app store was launched.
The free apps were first spotted by technology website The Verge. Apple hasn't responded to ABC News' questions about its motivation for giving away the apps or how long the promotions will last.
The app store was released July 10, 2008, with 500 apps. Ten million apps were downloaded in the first weekend. In May 2013, Apple announced it had seen 50 billion app downloads since launching the store.
Google's Android marketplace, or Google Play Store, has been on Apple's heels, with 48 billion app downloads in May. When Google's Play celebrated its first birthday in March, it also offered discounts on popular apps, movies, books and magazines.
