They have Photoshop on the iPad and Adobe says it’s “built with a no compromise in quality and performance”. Which means buggy as any Adobe product but useable. It really can’t get worse than Lightroom on an older intel Mac. An iPad Pro M1 also beat a MBP 16” with an i9 in Geekbench for multi core.
Video editing is also crazy good on an iPad Pro and iPhones.
