I stopped using it as much. I had some reports of using it for several hours per day, which as an adult with kids was sort of internally shameful and humiliating. Yet it kept happening despite efforts to prevent it.
The watch did a few things. It made it so I didn’t feel like I needed my phone around since my urge to have it was communication with my family or work. So, with that handled I could relax and leave the phone at home.
It also allowed me to see quite clearly how unnecessary my phone actually was. I rarely actually use my watch while out and about because the instances in which I imagined I’d need my phone were mostly false. The watch is useful, but maybe a few times per week rather than per day.
Finally it demonstrated that the utility I imagined my phone had outside of necessity was a lot more limited than I thought. Apps and cameras are cool, but not using them is, too. I really don’t care that my phone is gone when it’s gone.
So, I’ve gained up to hours per day of my life back and broke a terrible habit. I tried willing myself out of it but failed. Ultimately the watch was a great solution.
The trick is actually putting the phone away, though. If you carry both you’ll just use the phone anyway.
