Perhaps off topic? Ever think of an iPad version?

Have a look here:

Photolab for iPad (pro)

I’ve recently been dabbling into using an iPad for my photo editing needs. And to be honest, it feels super organic and right. The feel of using that pencil just on the photo itself is so good. But… the only viable option at the moment is using Lightroom. And Lightroom does not give me the same results as I get from Photolab. So DXO, I know this would be a really big venture but please do consider developing an iOS version of photolab. Editing on the iPad is the future for a lot of photographer…
