If your kid is serious about making videos, OBS is the graduation ceremony. It isn't an app; it's professional broadcasting software that happens to be free. It's the difference between drawing with a crayon and being handed a full oil painting kit.
It requires patience and a decent computer, but it transforms a kid from a passive consumer of content into a producer who understands how the machine works. Just remember: OBS records the screen, but it doesn't edit. You'll still need a separate video editor to finish the job.
