After enabling GPS tracking in the app (from the Menu > Settings page) your location will appear on the map as a blue dot.
Select any of the map pages from the app navigation bar at the top of the screen (Mobs, Paddocks or Tasks pages)
Select the target icon in the bottom right hand corner to zoom into your current location, which will be highlighted on the map as a blue dot.
Note: On android devices the zoom to your location button is in the top right hand corner of the map.
Move between blocks
Quickly move between blocks (if your farm has more than one block of paddocks) by tapping the zoom button, and tap again to zoom out to see all paddocks/block at once.
GPS Location of Other Users
You can only get the GPS of your own location on the App. As AgriWebb works offline, you're unable to see the locations of others within the app. However, depending on your device models and on-farm reception, you could use the likes of 'Find my iPhone' as an alternative.
