Though YouTube has supported picture-in-picture viewing on Android devices since 2018, YouTube told TechCrunch today that it plans to launch the feature to all iOS users in the U.S. on both iPhone and iPad. For now, YouTube is inviting Premium subscribers to test this feature, which lets users watch picture-in-picture videos in a mini player while browsing other apps. The testing period for Premium users ends on October 31, but YouTube does not have a timeline to share for when all U.S. iOS users will gain access to the feature.

Though this is a mobile feature, Premium subscribers must enable the ability to test it via the YouTube experiments website on the desktop. Last year, YouTube made opting into experiments a Premium perk.

If you scroll down on the experiments website, you’ll see “Picture-in picture on iOS” with the option to try it. Then, if you watch a video on the YouTube app, you should see a picture-in-picture display of the video when you navigate out of the app.

Once viewing a video via picture-in-picture, you can adjust where the video appears on your screen and how big it is. When you tap on the video, you’ll return to the YouTube app. If you lock your phone, the video will pause.

Some users have reported that you might need to delete and reinstall the YouTube app to get it to work.

This feature is different from existing picture-in-picture functionality on the YouTube iOS app because it allows you to continue watching a video even while navigating elsewhere on your phone. Similar features already exist on streaming apps like Netflix.
