It doesn’t work on my iPhone 13 Pro or my iPhone XS. This pin series and all record of them appear to have been removed from their site, so it’s possible AR functionality for these specific pins have been deleted from their database; but I cannot confirm this because the support url included on the paper that came with them is dead, and the only other support option is in regards to a collaboration request. I tried using that anyway, and didn’t receive a response. Pinfinity seems like a very disorganized company.
