One good reason is if you use something that can be synced with other members of your family, so if one of us has time to stop while on the way home from somewhere, everyone already knows what is needed without having to ask.

I uninstalled the Carl’s jr app because it’s notification sound was of someone taking a bite of something but exaggerated and more like what you would expect from a cartoon character. That shit made me uninstall it fast, I know I could have just disabled notifications, but my phone making that sound at me randomly when I was in the middle of something pissed me off.
