GeoFences in Blackberry Tracker

I've just added a new feature to Blackberry Tracker that allows you to be alerted when a device enters or leaves a certain area.

These GeoFences are defined by picking a center location and then creating a circle around that point. You then have the option of defining whether you want to be alerted when the device enters or leaves this area. Currently the only supported alert type is e-mail, but I'll be adding SMS soon too. If you want you can try the GeoFences out on the main page.

I'm still testing this feature out extensively so if you have any problems/suggestions you can e-mail me at blackberrytracker [at]

Also, I've moved the site off to its own domain now at
