But do nontechnical users care about the “missing” features? A lot of nontechnical users prefer simpler apps.
There is a version of Blender that was made for Android. It’s quite old, though. But if you’re competent enough with Blender that you’ve memorized all its keyboard shortcuts and workflows, you’re likely technical enough to get it working via Termux. But if not, Nomad Sculpt (on both iOS and Android), SpaceDraw (Android only), and several other apps can serve the same purposes.
Not sure why you listed video editing software and two different specific video editors, but Android and iOS both have Lumafusion. I’m sure there are other decent editors but I haven’t used them because Lumafusion is great. iPads do have DaVinci Resolve, though, for what that’s worth. If you care about using a FOSS video editor then you should care enough to install it via Termux. But let’s be real, most nontechnical users are probably happy using CapCut.
DJ software - Cross DJ is free. There are other alternatives. And there are web based DJ software apps like YouDJ.
Okay, and? What nontechnical user cares enough to use it specifically when they could use Microsoft Office, Google Docs, Polaris Office, MobiOffice, WPS Office, Collabora, etc., instead?
