Check with the product manufacturer,
Generally they're the ones that make the apps.

If you're thinking of a specific one you want to make, then you would need to develop it.
That's the best knowledge I have of it.

I was going to say I've been seeing a number of product variation plugins for Woocommerence, but I don't think they are that advanced, more just adding on to products. Thought I believe I've seen some that can customize products. I just kind of doubt that will be that advanced.

I agree, they probably had that made just for them.
