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.

Tracking works great but seriously, I don't need 275 notifications a day THAT I CAN'T DISABLE telling me that it's tracking my dog. Nice try Fi. I'm not talking in circles with a service rep. literally all notifications are turned off except for battery, signal loss and search party rinder. I get "Fi is active and monitoring [my dog]" I can dismiss it but it comes back LITERALLY in less than a minute. It is non stop and infuriating. Fix it or I will not be renewing my service.

Thanks for your feedback! We’re glad to hear tracking is working well, but we completely understand that excessive notifications is frustrating. You can manage most alert settings in the Fi App, but please reach out to us at (888) 434-3647 so we can look into the notifications you're receiving and make sure everything is working as it should.

overall, the app works wonderful. my only issue is that I keep getting notifications from my phone that this app is using very high battery usage. however, when I check the warning, it says zero battery used since last charge. I know that's not accurate because I take my dog with me everyday and I get a lot of alerts, not that I'm complaining. but I can't tell if this is what draining the battery on my new phone or not. The Galaxy says it is but the app report doesn't.

Hi Tommy, thanks for sharing this! The Fi App uses Bluetooth Low Energy to stay connected, but some phones may flag it for high usage due to background activity, even if actual battery use is low. We'd be happy to take a closer look and help optimize performance! Feel free to reach out to us at (888) 434-3647 🙂
