Fonts are problematic on iPads and iOS.
Some apps allow bring in fonts into apps, others not.
Take a look at an iOS app called Any font.
Most drawing apps will allow most of the common drawing app file formats.
Also, not sure if these vector drawing apps allow vector conversions of fonts/typefaces or not.
iOS is NOT Mac OS, so you would need to read the descriptions of these vector style apps to see if the app is capable of converting fonts/typefaces into vector paths or not.
At the very least, you could trace over a font in vector form for any vector app that can’t convert the text of font/typeface into a vector path.
Graphic for iPad does do text/type conversion
Inkpad and Touch Draw look to do this, as well as importing type.
Intaglio Sketchpad looks to have some form of text manipulation, too!
I don’t see any of this type conversion/manipulation in Vectornator Pro, though.
I mention Concepts drawing/ideation app ONLY because it covers lots of design disciplines and territories that make it a handy app for complete concept and ideation drawing and creation either in sketch form or more precise drawing styles and you may find this app a great app to just loosely or more accurately sketch or plan out drawings or type ideas or whatever level drawing/sketching and writing you do.
You will need to really read the vector apps descriptions to see which one/s of thess app/s will fill what you need them to do.
I can’t stress enough that the way iPads and iOS work is way different than how things are done on a Macbook with a full computer OS, like Mac OS X or macOS!
Multitasking on an iPad Pro is better, but still extremely limited.
There is no trackpad/mouse supoort. Only stylus and touch support on the iPad Pro,
The iPad Pro is no different from any other iPad or iOS device.
The “Pro” moniker is only about the Apple Pencil.
