About
Fi is a smart pet tracking ecosystem built for modern pet owners who want total visibility into their pet's safety, health, and daily habits. The platform consists of two hardware products — the Fi Series 3+ for medium and large dogs and the Fi Mini for small dogs and cats — paired with a powerful mobile app powered by AI. At its core, Fi provides cutting-edge GPS tracking that outperforms alternatives like AirTags and microchips by offering real-time location updates and a community-powered Lost Mode called Search Party, which alerts nearby Fi members to help locate a lost dog faster. Beyond location, Fi uses AI to decode your pet's full health picture. The app tracks movement and sleep patterns, monitors eating and drinking habits, and detects unusual behaviors like scratching, licking, and barking — giving owners early warning signs of allergies or discomfort. Fi Intelligence synthesizes all this data with breed-specific context to deliver personalized AI-powered health recommendations. Battery life is class-leading, with the Series 3+ lasting up to 3 months and the Mini up to 2 months per charge. Fi is trusted by millions of pets worldwide and offers a 1-month free trial with a refurbished device, making it easy to experience the full platform before committing to the $19/month subscription.
