Seems like there's a few android equivalents:

And even one that claims to work with sound:

EDIT: Actually there's an enormous number of apps like this, many released very recently with similar style etc. Weird.
Tried the first one and it doesn't seem to work (dots don't respond to motion), and is absolutely riddled with intrusive ads. The one that another commenter left which is on F-droid is much better
It's been rumored that Google would build it into Android for years:

I've tried some of those Android equivalents and they seemed to work on any motion, not on acceleration like the Apple one.
I've found Kinestop to be much more effective and immediate than Apple's, highly recommend.
Be careful with these apps. The permissions they ask for are quite expansive.
If you're like me and want an open or non-google-play alternative to these, this is available on F-Droid: https://f-droid.org/en/packages/dev.davidv.motionsickness/
I can't vouch for it (yet) but am going to give it a try!
