Geofencing for ring/simplecommands/SmartThings?

So I finally have my ring alarm working with my SmartThings automation and I have managed to get from it everything I had with my previous alarm.com automation. The only thing I am now trying to figure out is how to make it send me a push notification or an sms if both me and wife are out and forgot to arm the system. With my previous alarm.com automation, there was a geofence which If crossed when both my wife an I are out, would send a reminder to our phones.

Why not instead set it so if both of you leave the house it auto arms the system? I have a routine set up and it turns off lights. Locks any doors, and sets mode to away automatically.

That’s not gonna be ideal since we do get our in-laws or my parents come home often and stay over even when we leave for work etc
