Fi is the smart dog collar that combines GPS tracking, activity monitoring and escape alerts with long battery life.
Fi builds GPS-enabled smart collars for dogs, pairing precise location tracking with activity and sleep monitoring. Its network-assisted location and escape alerts notify owners the moment a dog leaves a designated safe zone.
The Series 3 and later collars deliver multi-week battery life, and the Fi app turns activity data into fitness insights and community challenges. Subscriptions cover cellular tracking; for owners of escape artists and adventure dogs, Fi has become a category-defining pet wearable.
Losing a dog is every ownerβs nightmare, and conventional GPS trackers historically failed on battery life β dying before they were needed. Fi engineered around that constraint: multi-week battery life on a collar that tracks location nationwide over cellular networks and alerts the moment a dog leaves a safe zone. Activity and sleep monitoring extend the value to daily health, and community features support lost-dog recovery efforts. The subscription model funds the cellular connectivity that makes real tracking possible. For owners of escape-prone or adventurous dogs, the combination of battery endurance and fast location updates is the entire product promise.
The health side extends value beyond emergencies: activity and sleep trends help owners notice changes early, and the community has turned lost-dog recovery into a coordinated, networked effort.
Platforms in this category win on breadth and integration: they consolidate fragmented operations onto a shared data foundation, then apply AI where it reduces cycle time and cost without forcing organizations to rebuild everything around the software.
Collars are purchased with a required subscription plan for cellular tracking; a trial period is included.
Dog owners who want real-time location safety and health tracking in one collar. Also fits owners of working and sporting dogs trained across wide outdoor areas, and to households that want health and safety monitoring in one device.
A trial period is included with the hardware; ongoing tracking requires a paid subscription.
Fi centers on its consumer app; there is no broad public developer API.
Compared with Bluetooth trackers, Fi offers true long-range GPS tracking; compared with generic pet GPS, it wins on battery life and community features.
