I used to lose my phone more whenever I went out drinking until I got the watch. That's because I used my phone to tell the time. So it was in-and-out of the pocket. Now, I keep my phone in my bag and I haven't lost one in two years.
That's especially true when it comes to working out. I have a small slice in the day to workout and I don't want to fiddle with stuff.
It could be that I'm feeling residual frustration from attempting to try Fitness+ on an iPad which I never figured out. I just don't understand why I need a watch to view workout videos. I guess that means I'm not the target market. Thankfully there are good alternatives.
