Bug fixes and performance improvements.
Description
Fi Series 3+ is the world's smartest GPS dog collar—now powered by AI.
Paired with a Fi collar, the Fi app brings you even closer to your dog. Track their location, monitor activity and health patterns, and get alerts if they ever leave a safe zone. It's peace of mind for the best pet parents out there.
FEATURES
GPS TRACKING
On vacation? Friend walking the dog? Instantly track your dog's location no matter where they are. Fi gives you the confidence to know they're safe from anywhere, anytime.
STOP ESCAPE ARTISTS
Designate safe zones around your home or dog's favorite places. If they leave without a trusted person, we'll alert you immediately. So if they wander anywhere, you'll be the first to know.
ACTIVITY MONITORING
Track your dog's step count daily and start streaks by achieving custom goals you set. Then see how they compare with similar dogs in the Fi community. Every step goes a long way toward keeping them happy and healthy.
AI BEHAVIOR INSIGHTS
Fi Series 3+ tracks more than just steps. Spot trends in activity, rest, scratching, licking, drinking, eating, and barking so you can stay in tune with your dog's health and habits, every day.
LOST DOG MODE
Never lose track again. If your dog goes missing, activate Lost Dog Mode to turn on rapidly refreshing live location updates until they're found.
BATTERY LIFE
With best-in-class battery, our collars lasts up to 3 months on a single charge. No other collar even comes close.
SUPPORT
Need help? We're here for you and your dog. Our support team is just a chat or phone call away when you need.
APPLE WATCH INTEGRATION
With our all new Series 3+, you can view your dog's location and activity directly on your wrist, so you're always connected, even without your phone.
OUR COLLAR
Available in 4 different colors and 5 different sizes to fit dogs of all sizes.
Fi works best when connected near a Bluetooth connected device with the Fi App or the provided charging base. The latest iOS version is required to run Fi. Learn more about what we're building at: www.tryfi.com.
