The Geofence iOS app is a simple tool to trigger a webhook every time the device on which the app is installed comes close to the configured target.
You can configure the exact location to monitor, and the radius around this location which marks the “boundary”, or “geofence”, to monitor. When the device enters the geofence, the webhook will bet riggered. To overcome fluctuations when you move around the geofence, a cooldown period is started when first exiting the area inside of the geofence. When you re-enter after the cooldown period, the webhook will be triggered.
