- Its default GPS check-in radius is 5 km; dated correction stamps can cover failed location checks but do not earn ranking points.
Field notes
The site sets a default 5 km GPS check-in radius, with custom settings for some broader hot-spring destinations. It says all 2,148 currently eligible destinations have GPS center points, though not all have been field-verified; 2,034 use a shared stamp because they have no dedicated cat. Correction stamps can count toward collection rewards, but not leaderboard points.
