Introducing Fi, the world’s first LTE smart dog collar.

Paired with a Fi collar, the Fi app brings you even closer to your dog. View your dogs location and activity levels on the app, and be alerted if they ever escape from a designated safe area. The smartest pet parents choose Fi.


On vacation? Friend walking the dog? Instantly track your dog’s location no matter where they are. Fi gives you the peace of mind to always know that your dog is safe.

Make sure your dog never escapes from your backyard. Fi lets you designate safe zones around your dog’s most popular residences, whether that’s your house or your grandma’s, and we’ll alert you if they ever leave home without a walker. So, if your dog runs out the gate you forgot to close, you’ll be the first to know.

Fi measures the steps your dog takes and compares it to other dogs wearing a Fi collar, so you’ll always know how much exercise they’re getting, and how much more they need. Set daily goals to hit and view all previous walks and activity. Keep your dog happy and healthy with Fi.

We’re putting an end to lost dogs. If your dog’s got out, enable Fi’s unique Lost Dog Mode at the click of the button. A red light will appear on their collar, and the collar will report its location every minute as they move. Make sure you never lose hide and seek again, with Fi.

Introducing the world’s first LTE dog collar. Running on a brand new LTE-M network, you’ll only receive the most accurate location reports and always know where your dog is.

If we lose our dog the last thing we should worry about is battery life. Part of the reason we built Fi is because we didn’t feel that other smart collars offered enough value to us dog owners. On average, our collars last 3 months between charges. So, it’s another thing you don’t have to worry about.

We care about your dog as much as you do. With live agents ready to talk to you whenever you need, we’ll be right by your side for your journey with Fi.

Coming in two different colors and three different sizes, Fi works for any dog over 20lbs.

Fi works best when connected near a bluetooth connected device with the Fi App or the provided charging base. The latest iOS is required to run Fi. Learn more about what we’re building at:

So worth it!

I got this collar primarily as an activity tracker for my medical alert and mobility assistance service dog, Maui. I’m beyond impressed by its capabilities in this department! I was surprised at just how much I love the GPS functions as well. As a university student, the GPS is phenomenal for whenever we go on hikes (the campus is quite expansive with various terrain and water nearby) as a safety measure and for my peace of mind when a trusted friend is exercising Maui for me when I can’t. The app is incredibly easy to use, the base station easy to bring with me if I’m off campus for multiple days (the collar’s battery lasts longer when there is a local base station rather than relying on GPS 24/7), the collar is waterproof for all intents and purposes, it charges quickly, the fitness metrics are easy to understand and the reassurance of knowing where he is if something were to go horribly wrong is so beyond worth it to me. The ONLY downside to this product after ~6months of use in my eyes is that the metal (plastic that looks like metal I think) GPS transmitter on the collar is being dinged up by Maui’s metal ID and rabies vaccination tags. It’s just a very minor aesthetic thing that you can’t see unless you’re basically holding it but I wish it were replaceable if need be (it might be... I don’t know). I will definitely continue using this collar and the GPS service through Fi for years to come!

Better than al of them!

So I’ve tried a few gps collars. The one I had before FI was LINK AKC. Fi’s ability to hold a charge more months alone makes it worth it. Being able to set safe sones on the fly is also really great and helps reduce unwanted alerts. I recently adopted a 2 year old Australian Cattle Dog , and Fi has made training to be off leash so much more less worrisome. My 10 year old also likes to walk her on his own, so having the collar helps ease my worries for both my babies. So far our ACD has been doing great, and the light feature works wonderfully when she’s playing off leash at night. I am also impressed with the waterproofing. Libby (our pup), jumped in a creek to catch some fish, and for a brief second I thought “oh no! Her collar!” , and then I remembered that Fi is awesome and I didn’t have to worry. The free month of GPS for inviting friends was a nice surprise! so thank you! 🙏 Can’t wait to see what new features and updates come along. If there is a way to set alarms and reminders for when she is due for her walk, that would be great. Or if the Fi app can recognize patterns, and create reminders based on past walks/routines, that would be awesome too. 🐾🐾🐾👍🏻🙏 and maybe teaming up with the app WAG- would be cool too. Like maybe offer a discount on wag walks if they have a Fi collar that coordinates etc. That way when a wag walker comes to walk your dog, it recognizes the walk as safe. Just some thoughts!

Reports Car Rides As A Walk

Every time my dog is in the car the device reports the drive as a walk. I even take the collar off in case my dog is moving around as it says in their support materials. Still the same. This is so unacceptable! I emailed customer service who tried to tell me this was normal. NORMAL! The device is logging miles and miles of activity describing it as a walk when I’m driving down the road. Their customer service says it’s the algorithm that figures all of this out. Really? This algorithm can’t see that my dog would be incapable of walking 60mph? And this is deemed normal? Imagine if my Apple Watch were to log exercise minutes every time I was driving in the car? This is NOT normal. On top of everything else, this device is advertised as an activity tracker! It’s not living up to the marketing this company advertises. It would seem like an easy fix to allow me to reclassify the activity, or even more simple, to just delete the activity. This is unacceptable. It should not be considered normal. Because of this glitch the data across the whole platform is suspect. They’ve had several years to fix this but haven’t done so. WHY?

We're really bummed that you're not having a good experience - we actually recently released an app update that should resolve the car ride issue!
