As mentioned earlier today on list, the Wikipedia iOS app has a major update, v5.8.0, now available on the App Store:

This release adds Reading Lists, which allow you to organize your saved pages into folders. You can now also sort and search all your saved articles, along with the new lists. And most excitingly, users who log in and opt-in to syncing can use this feature across mobile devices and platforms. Save an article on your phone to read that night on your tablet. Cross device rabbit hole!

Thanks to the Android and Reading Infrastructure teams for blazing the trail and building the MediaWiki and service layers to enable this much requested feature.

As always, thanks to our volunteer contributors, bug reporters, translators and testers. Special shout out to volunteer dev Michalciurus for his multiple code patches this version.

Cheers,
Josh Minor
PM, Wikipedia for iOS
