I made a watch-only fidget: 900 beads that pour when you tilt your wrist
I made this. Beadfall is a handful of beads that live inside an Apple Watch. Tilt and they pour. Hold still and they settle. Flick and they climb the wall and rain back down. Real physics, 900 beads at 60fps on the watch itself, not a looping video.
Watch-only, no iPhone app. $2.99 once. No account, no ads, no IAP. There is no network code in the app at all.
Honest caveats: sound is off in v1. The screen can dim while you tilt because watchOS reads that as looking away. A tap wakes it. Uses more battery while it is open, then it stops.
I have 10 promo codes. If you actually want to try it, say so in a comment (which Watch you have is useful) and I will reply with a code. No upvote needed.
