So you felt nothing when they were briefly on DS9 and stopped by Quark's before getting lost in the Delta Quadrant? You bring dishonor to your house! (In fact, Tom gets in a barfight with Quark (not shown on screen, unfortunately) in that one timeline where Harry was never assigned to Voyager.)
Just kidding about the "dishonor to your house part". Honestly, I like some of the fun 90s Trek had with crossovers, especially how VOY sort of rehabilitated Barclay. Honorable mention to that thing where Bashir helped Data have dreams. I guess O'Brien and the eventual Worf being mains on DS9 count as well; I think despite his flaws getting really annoying, Worf gave us an excuse for the fun Klingon political plot lines.
As an actual question, though, do any of the following apply to you?:
- Didn't also watch DS9 as a kid.
- Were watching Voyager out of order, only catching random episodes, etc.
- All of the above
I haven't researched this (I don't have kids), but out of curiosity, what type of mobile device is your daughter using? Also, I think PiHole is a solid recommendation like others recommend.
Otherwise, from a quick Google, I don't know of anything that can integrate both Linux PC and mobile phone screen time. Honestly, this sounds like a fun project I could implement someday if I ever had the will. However, for right now, in terms of screen time all I can think of is reading system logs (perhaps via SSH) to manually analyze your daughter's screen time.
