About Fi: More Than a GPS Dog Collar
Fi was founded with a simple mission: to help keep dogs safe and bring lost pets home. Today, Fi has evolved beyond GPS tracking to become an all-in-one pet safety and health platform, combining real-time location tracking, escape alerts, and AI-powered health and behavior insights.
Through the Fi app, pet parents can track their dog’s location, monitor daily activity and sleep, and better understand everyday behaviors like barking, scratching, and licking. By turning everyday data into meaningful insights, Fi helps owners recognize changes in their dog’s routines and take a more proactive approach to pet care.
And that technology is making a real difference. In one year alone, Fi helped bring 67,889 lost dogs home.
Fi’s lineup of smart pet trackers includes:
- Fi Series 3+: An all-in-one GPS dog collar with real-time location tracking, escape alerts, and AI-powered health monitoring.
- Fi Mini: A lightweight GPS and health tracker for dogs and cats that attaches to virtually any collar or harness.
- Fi Ultra: An advanced GPS dog tracker featuring T-Satellite with Starlink connectivity for adventures beyond traditional cellular coverage, recognized as one of TIME’s Best Inventions of 2026.
