Adobe Illustrator is finally available on iPad, after its unveiling in November 2019. The app had been in testing for some time, and is now available for all Creative Cloud subscribers.

After Photoshop for iPad, Illustrator is the second professional app by Adobe to be completely reimagined for multi-touch and Apple Pencil. Despite the lackluster reviews for the initial Photoshop release on iPad, Adobe continued working on improving it, alongside Illustrator, which utilizes a similar user interface.
