What should I do with my old iPhone XR?

I just upgraded to a 13, but the trade-in was only $80 and I thought I might find something better to do with it than just get $80 back, so I'd love suggestions. Remember, it doesn't have cellular access anymore, just wifi. Does anyone have any good ideas for what to do with it? A friend suggested a dedicated GPS for my car, which I would obviously have to upgrade on occasion, but I can do that from my garage. Slightly annoying, but possibly useful. Any other ideas?

Yes, I know, throw it out or use it as a coaster. Ha ha. Very droll.
