Guidance Needed for iPADS/Software for ART/NFTs

I was under the impression that you didn't need to create the NFTs on any specific type of device, so long as the final NFT is viewable on the device it is being sold for/to?

I mean, you can pretty much open up photoshop and create an NFT that will be useable on any device, as long as you have the correct dimension for said NFT to be cross device compatible

I know there are several apps available for creating NFTs on devices such as cell phones, tablets, etc, perhaps look into those apps and see if there is any major advantage of creating device specific NFTs vs multi-device compatible ones

You are correct with all of that. We've just decided to use iPAD Pro tech to make our NFTs because there are so many apps out there.

We also plan to use it for drawing, photography and music some of which will be looped into NFTs.

Have you worked with any iPADs?

Whats your take on the need for ETH when making NFTs and how much?
