3D modeling for iPad - What are you using and why?

I’m looking over all the apps for iPad to create and modify existing models. But there’s so many and some have very costly licenses to get the features. I’m leaning towards Nomad Sculpt, but figured I’d ask for opinions and suggestions before buying it.

Printers - Bambu A1 w/AMS Lite and an A1 Mini.

Things I’ve used on my computer:

Tinkercad- it’s good for the basics. But doesn’t really take advantage of the pencil and lacks features. Blender - fine on my computer for most things, but not for iPad. Fusion 360 - same as Blender, not for iPad.

Besides modifying existing models, I want to create more mechanical ones. Things that will flex or have parts that snap or screw together. Looking forward to the feedback!
