Mobile device systems and methods for monitoring geofences cache a subset of geofences within a likely travel perimeter determined based on speed and direction of travel, available roads, current traffic, etc. A server may download to mobile devices subsets of geofences within a likely travel perimeter determined based on a threshold travel time possible from a current location given current travel speed, direction and roads. Mobile device may receive a list of local geofences from a server, which may maintain or have access to a database containing all geofences. The mobile device may use the cashed geofences in the normal manner, by comparing its location to the cached list of local geofences to detect matches. In an embodiment, the mobile device may calculate or receive from the server an update perimeter, which when crossed may prompt the mobile device to request an update to the geofences stored in cache.
