Unfortunately, you have to own an iPhone or an iPad in order to use a HomePod or HomePod Mini. This is because of the way Apple authenticates requests — everything goes through your phone, making it essentially the hub of your digital life within Apple’s ecosystem. If you have an iPhone, of course, it’s not a big deal and you may never know about this limitation, but if you don’t, you’ll soon be very frustrated if you’ve purchased a HomePod.
