Today - Fi unveils a revolutionary GPS and health tracker that transforms any collar or harness into a comprehensive pet safety system. 

Fi Mini weighs just 0.56 ounces, making it the lightest, smartest tracker ever designed for dogs and cats—and at less than $12/month with hardware included, it's the most affordable full-featured GPS and cellular tracker on the market.

All the Power of Series 3+, Now Pocket-Sized

Fi Mini brings the same advanced location precision, escape alerts, and activity tracking you trust in Fi's flagship Series 3+, now in a miniature clip-on device that works with your pet's existing gear. No collar replacement required. Fi Mini launches with nationwide coverage on the Verizon LTE-M network.

"Pet parents shouldn't have to sacrifice style for safety or replace a collar they love just to get professional GPS tracking," said Jonathan Bensamoun, Founder and CEO of Fi. "With Fi Mini, any collar becomes a smart collar. You keep the gear your pet loves—we add the technology that keeps them safe."

Finally, Cats

Fi Mini is purpose-built to serve a wider population of pets—especially those previously excluded by the size and weight of traditional GPS trackers:

Universal Fit Three flexible attachment systems accommodate any collar or harness from 3/8" to 1" wide.

Tiny but Mighty At just 0.56oz, Fi Mini is perfect for small dogs under 10 pounds—and finally brings real GPS tracking to cats.

Small Size, Serious Power

Despite its ultra-compact form, Fi Mini delivers full-scale smart tracking performance:

  • Real-time GPS live tracking & escape alerts
  • Nationwide LTE coverage (Verizon LTE-M)
  • 3-week battery life with easy USB-C charging[can be paired to a Fi Base for extended up to 3 months battery life]
  • Seamless health tracking powered by Fi's award-winning platform
  • IP68 waterproofing

Future-Ready with Fi Mini+

Each Fi Mini is pre-equipped for a forthcoming upgrade to Fi Mini+, a premium software suite that unlocks AI-powered behavior detection (barking, eating, drinking, scratching & licking), mirroring the advanced insights offered by the Fi Series 3+. The software update will be available to Fi Mini customers this fall.

Available Now

Fi Mini is available now at tryfi.com for $129/year—including the hardware and a full year of Fi Membership. Orders placed will begin shipping September 1st.
