I've had the same thoughts with your daughter from the first time I read you're article about how the Apple Watch can help with your mininalism journey. However, I don't put value judgment on that. If you find an Apple Watch adding value to your life and you are intentional about it, then that would work for you. Minimialism is different from one to another. I gave my smart watch last two months ago since in my Minimalism journey, I find it more of a distraction than it adds value.
