I'm trying to figure out how I can send a notification to both phones when they reach a 6ft range from each other. I know that GPS is too wide of a range and so if wifi, I'm currently trying to use Bluetooth Low Energy because I heard it was more precise please let me know if there is any way I can go about this.

According to this blog, the signal range of each Bluetooth version varies. so it's difficult to find distance just by signal strength alone.
Solution: The proximity between the two devices can only be known when they are connected, as soon as they are connected request the user to stand 6 feet away from the other user and note the signal strength. note: it won't be accurate. it totally depends on the environment
Here is a thread to find the signal strength. Hope this helps
