Notes

While the free Apple iOS Notes apps appears to get better with every iOS iteration/version, it STILL ONLY gets upgraded when a brand new iOS version gets released.

This is a default free app that is more like a “showcase” app for what a sketch or drawing app could be.

If you need something with more comprehensive features and better zooming and more precision there are lots a more paid, “professional” sketching/drawing/painting apps for iPad and Apple Pencil.

For better sketching apps you could look at

Tayasui Sketches ( Pro )

Tayasui Memopad 2

Colorbox ( Pro )

ColoredPencil

AutoDesk Sketchbook

Apple is quick to tout new and great features of a new product/software/OS, but Apple is less than forthcoming when it comes to changing or removing existing or previous features of a device/product/OS.

It only appears in landscape mode.

Tapping the 2 arrows brings up full screen.

You also have to be in List View, not Grid View.
