Noob question - Can you do both Smart Things app and Home Assistant?

I just finished wiring up the 6 zone module. I am trying to understand my options. I do not have Home Assistant set up yet, but I am familiar with it. Can I set up the Smart Things app and run it in conjunction with Home Assistant? Or is it one or the other?

I want remote visibility to the alarm, I assume the easiest is Smart Things app, but I wanted the brain trust to confirm I cannot have my cake and eat it too by having both.
