@ivanidea, I don't think you need 2 iPhones--just 1. We just bought the 4 pack of AirTags during Prime Days, and when I set them up, they are all on my phone. You get a chance to "name" each tag and then each of them shows up on the "Find My" app on your phone. As long as you have a way to keep the tags straight (we ordered some holders), you can see where each tag is. Pretty slick!
