My SO can just call me, and they do about every other day when I'm inevitably stuck in traffic due to some accident during rush hour.
My SO and I call each other very frequently. It takes 10s to call and ask me if I'm stuck in traffic or something. Maybe it takes 5 to check an app, but saving a few seconds isn't worth the unlikely but possible downsides.
Where's the upside vs alternatives that don't have those extra issues?
