The App Store turns five years old this week, and 10 major, critically-acclaimed and fan-favorite apps are going free to celebrate. They include Infinity Blade II, Barefoot World Atlas, Traktor DJ, and more.

In honor of the App Store’s 5-year anniversary, Apple has compiled a list of what it considers the 10 best third-party apps of all time, and best of all, these ten apps are free. Grab them fast, because the freebie sale only lasts one week: Monday, July 8th through Sunday, July 14th. After that, the ten apps go back to their regular prices.

There are some truly terrific apps here, including several that typically fall on the pricier side of the App Store’s catalog. Pro music mixing app Traktor DJ, for example, usually sells for $20.

Apple hasn’t formally released their list yet, so we don’t officially know all 10. But the following apps are confirmed to be part of it, and we’ll update this page when Apple makes its official announcement.

Update: Apple has updated the App Store with a page explaining that these anniversary-celebrating apps are not “the best apps ever,” as previously expected. Instead, they’re listed as “five groundbreaking apps” and “five landmark games.” Since the App Store separates them this way, I’ve updated this page to list them the same way, as you can see below.
