Adobe CC aps on ipad air

There seems to be a version of illustrator in the App Store (just search for Adobe), but I suspect like many programs, the app is a simplified and skinnied down version of its parent program.

Adobe has its own forum so you may wish to ask there to see if the app does what you need it to

No.

iPads are NOT full featured laptops and DO NOT run full featured Mac or PC apps.

There are only early versions of what Adobe is calling full Photoshop and Illustrator for iOS/iPadOS, but these are still relatively new to iOS/iPadOS and are still being updated and developed over time.

Adobe Photoshop for iOS/iPadOS is about a year old. Adobe Illustrator for IOS/iPadOS was just introduced sometime in mid to late 2020.

There are still a lot of missing features in these iOS/iPadOS versions of PS and AI.

There are many great third party apps for iOS/iPadOS that can do what Adobe Photoshop and Illustrator do, but if you are dead set to ONLY want to use and run full Adobe suite apps on an iPad, then you need to look elsewhere, like Microsoft Surface/Surface Pro tablets which have touch and run full Windows and full Windows applications.

Sorry & Best of Luck to You!
