Image Segmentation on Ipad

I am curious if there is someone segmenting images on an Ipad or tablet type of device with pen support.
For me, it seems like a good choice to obtain high quality masks.
What apps could do this?

@tcapelle I’m also looking for this, I have just tried but it won’t even load the interface on iPad. Did you find something?

I find a Surface Pro good for this.
