Halo Collar is a free lifestyle application for iPhone developed by Protect Animals With Satellites LLC. It is the world's greatest smart fence system that allows you to create virtual fences within the app, and keep your dog safely inside. The app includes in-app expert training, real-time safety and activity tracking, and instant communication with your dog anywhere, providing the best protection for your best friend at home or on the go.

The Halo Collar uses world-class global satellite GPS and GNSS systems to locate your dog(s) and works autonomously to provide instant prevention and encouragement feedback to keep them safely inside their smart fences, direct them back in if they leave or call them back home, wherever they are. You can create up to 20 unique Halo Fences virtually anywhere in the world, and the fences are stored right inside the Halo Collar, which means no wires, no digging, and no hubs are necessary. With intuitive boundaries, Halo Beacons, and phone notifications, you'll stay up-to-date about your dog's safety without having to worry.
