I think, the best png tuber software out there - highly recommend for starting out or getting more fancy animations to your existing png. There's also an option to donate olmewe before downloading (it's otherwise free!!)

Have been using this since I first got my iPad Air (although previous version of this so now it should be even better!!), and the best part is that it has the pencil holder as well as a working charging side (for Apple Pencil 2). Yellowing only came in after about a year of constant use. I recommend giving light washes to keep it looking nice for longer (in my case, lasted me 2 years).

This literally saves your apple pencil if you have one, you might find better deals for more in a pack but this is the exact one I personally have. They last anywhere from a week to a month of use per nib cover from my experience (that's a LOT of artworks)

Super good for the price, also great for starting out as you won't need a sound board cause it's USB ;D
