Hey there, I hope you're doing well.
As my friend LongHiker said, Samsung's built-in Reminder app and Bixby can handle this with ease.
To do this in the Reminder app, open the Reminder app>Press menu>Settings>Enable places
To make the actual location based Reminder, open the Reminder app>press the + button>Name your reminder>Enable location and enter or search an address.
I've attached screenshots for your reference. I hope this helps.
when I search Samsung reminder app I don't see anything obvious that shows up
