About this app

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. Learn more about what we're building at: www.tryfi.com.

When Fi3 came around with the subscription model it was supposed to include hardware upgrades. They had raised the price, where the earlier models you bought the device and paid for the service, for a time, a reduced rate. So they have an actual upgrade which they claim faster seek times, a serious need, they have pulled the free hardware upgrades, right after my subscription reupped. And battery life went from months to maybe 2 weeks. The Apple move. Planned obsolescence. Screw us.

App is terrible now. You can only open the app while connected to the Internet. Bluetooth functionality is dead. Collars no longer connect to phone via Bluetooth. No way to see even collar battery status without Internet, even if you're on the same wifi network as the base. So if you lose Internet, you lose everything. We will likely not continue service because of these issues.

Worked very well when first purchased 7 months ago. Over that short time, the app has become progressively slower in tracking. Takes almost 2 minutes to Track Lost Dog, that's unacceptable. Also, while walking, the yellow location tracking line in the app can make exaggerated movements seemingly at random, making it unreliable at times to truly know your dog's location.
