You may be striking the goldmine with this app. There's a lot of sentiment about the effects of tech on children and also parents spend money like no one else.

On a personal level I'm interested too. My son is too young, so we only watch youtube together, even then he's very susceptible to the attention-grabbing recommendations. "Theater mode" helps put the recommendations off-screen. "Don't recommend channel" helps a curate the feed a little bit.

But ideally I should be in control of the whole interface.
