Hi,
The wayspots with a white outer ring will not be used as either Pokestops or Gyms as they are in an already occupied cell.
The reason is explained at https://community.wayfarer.nianticlabs.com/t/why-an-accepted-wayspot-may-not-be-used-in-pokemon-go-s2-cells-and-pokemon-go
What’s the app name? I want to know about that square area. to know im gonna put another pokestop and not put it if already added
It’s the official Wayfarer map with an unofficial community-made S2 cell overlay. You can search for “Wayfarer Tools” to find more information.
Just keep in mind that S2 cells are a community-discovered Pokémon GO inclusion rule, not an official Wayfarer eligibility rule, and Wayspots must always be placed at their correct real-world location.
The link above is likely to be removed as we are not allowed to link to 3rd party tools.
A google search for “Wayfarer Tools” will find what you are looking for.
Remember that even if it doesn’t become a Pokestop or Gym it may be used as a Dynamax Powerspot.
