VTubing-esque software on iPad or Linux

[randomtangent]

hi, i've just been wondering about this.

i have an M1 iPad Air, so i'd really take that over my laptop, because my laptop isn't a gaming computer nor is it new, lol
my M1 iPad Air has VRoid Studio already on it, so that's what i use to create my model :P

using Steam with Proton (no matter which version) it never starts the VTuber applications cuz they so badly need DirectX 11, in which... i'm on Linux lmao. and this laptop chugs on Windows 10 too, which is why i have MX Linux on it.

anyways, is there anything for the iPad? i don't want to stream, if anything i just want a basic little area where my model can be in and look roughly at the camera, hold a microphone, and i can rant into the microphone of my tablet? especially good if it has some form of tracking, even if it's really basic?

my idea is just to use the Clips app to do basic video editing (if at all lmao) and probably upload to my own static site eventually? but for now it's mostly just a concept to let it online.
i wanna just have her in a setting similar to "VTuber Maker" (ik generic name but that's the app name and i got it on Steam) but... i can run it on my tablet, and use my VRoid model with it?

edit: especially in Australia, cuz half of these are Japan-only. i can barely understand a tiny bit of broken Japanese, so obvs i can't really use it unless it's in English lol. i just got FACEMOTION3D too, it seems pretty good just off the bat but i dunno how good it is lmao
i might add a guide if i can get it to work well (^_^)

adding onto this now~

FACEMOTION3D works well enough for iPads, though i think it'd need an M-chip iPad, any A-chip would probably struggle to a degree. my M1 is good but gets a tiny bit of stutter occasionally.

anyways...

FaceMotion3D isn't the best in terms of... being free? it's freemium, so basically you're forced to pay just to use VRM models. it could be a subscription, but at least they have an option for a lifetime purchase...
also they only allow you to record 5 seconds of footage unless you pay again. there's multiple things to pay for. so just keep that in mind if you get it.

and you don't want to export as FBX - it's mostly just a text file.
at least as far as i know, you need to actually record the screen (tap n hold it to enable mic) and tap to hide all the buttons. then crop it in the Photos app.

in my experience i need to upload the MOV file to a cloud storage app, so i can download it onto my Linux PC and edit it in OpenShot from there. i recommend this for pretty much anyone with Windows, GNU/Linux, or etc. if you have Mac then i'd assume it'd be easier since it's in the Apple ecosystem.

ugh why are all Mac, iOS, and iPadOS apps always paid-only? it's getting on my nerves...
FaceMotion3D seems to be (if not literally is) the only tracking software available for iPadOS at least in Australia (my country) so it is what it is i guess.

also along the question of why are most Apple apps paid-only? i know at least on Mac there's some options for free n open source apps, but iPads and iPhones always seem to get the short end of the stick. especially the App Store itself being filled with AI slop and exploitative rubbish, jailbreaking isn't always an option for anyone too :P
@Melooon i think you'd be good at answering this?
