Fi is a free lifestyle app developed by Barking Labs Corp. The app is paired with a Fi collar, the world's first LTE smart dog collar. The app allows pet owners to view their dog's location and activity levels on their iPhone. The app also alerts the pet owner if their dog ever escapes from a designated safe area.

Fi provides GPS tracking, so pet owners can track their dog's location no matter where they are. The app lets pet owners designate safe zones around their dog's most popular residences, whether that's their house or their grandma's, and alerts them if their dog ever leaves without a walker. The app also measures the steps their dog takes and compares it to other dogs wearing a Fi collar, so they'll always know how much exercise their dog is getting.

Fi offers a unique Lost Dog Mode that enables pet owners to locate their dog easily. The collar will report its location every minute as they move, and a red light will appear on the collar. Fi runs on a brand new LTE-M network, providing pet owners with the most accurate location reports. The collar lasts up to three months between charges. With live agents ready to talk to pet owners whenever they need, Fi is an excellent tool for pet owners who want to keep their dogs safe.
