It uses Apple's ARKit so it will only work on iPhones. And you need iOS 11 and at least an iPhone 6S or a very recent iPad for it to work.
Google has announced some Android AR stuff so when they roll they out, we will look at making this stuff work across both platforms. Sorry it won't work for you yet!
I always wait for the first minor version bump before installing a new iOS release. Not this time! I can't wait that long to play with what you've built.
(I'd like to read more about it, too, but your Medium link upthread is 404ing...)
Hey! Sorry -- we should've made this clearer. ARKit only works on devices running iOS 11, and some particular devices at that:
iPhone 6s and 6s Plus, iPhone 7 and 7 Plus, iPhone SE, iPad Pro (9.7, 10.5 or 12.9) – both first-gen and 2nd-gen, iPad (2017), iPhone 8 and 8 Plus, iPhone X
I think these are the ones, at the time of posting this comment.
Haha yeah, Expo itself generally works on both iOS and Android, but this particular demo in Expo works on iOS only since it needs ARKit. Here's an edit of the demo to just use a standard THREE.js camera and scene and not an AR one: https://snack.expo.io/rJCl4mnib It should work on Android. You can still edit the code (like the box dimensions) to see the changes immediately!
