Apple CEO Tim Cook described the new features on stage during the opening hours of Apple's Worldwide Developers Conference.
The most interesting changes coming to the App Store are new tools for developers: app bundles, videos in app listings, and the integration of TestFlight.
There are some minor improvements to searches coming, as well, including some new tools for users.
Tools for developers
With app bundles, app makers can now bundle their apps together and sell them at a discounted price, allowing users to purchase multiple apps at once with just a few taps.

Devs will also be able to embed short videos in App Store listings to show off apps' features - much like in Android's Google Play store, where developers can embed YouTube videos.
And the official integration of TestFlight into iOS will likely make it easier for developers to let users test early, in-progress versions of their apps before they're released.
Searching for improvements
Cook also showed off some improvements coming to App Store searches.
iOS users will soon have access to a new "explore" tab where they can browse through categories and sub-categories, with the aim of making it easier to discover the right apps.
Users will also be able to view trending searches to see what's popular, and searching will be faster, especially with new continuously scrolling lists of results and a "related searches" feature.
Finally there's a new editor's choice logo to highlight featured apps that Cook said will really pop.
"We are really investing a ton in the App Store," the CEO said, adding that these improvements will arrive in the fall.
