Fi is a company that practically reinvented the dog collar by infusing it with numerous modern technologies and focusing primarily on equipping it with enough features to allow all dog owners to locate their pets and prevent them from joining more than 100 million dogs that go missing every year.

The project was started in 2017 by Johnathan Bensamoun and Loren Kirkby and quickly raised 10 million dollars from investors like Lerer Hippeau, Freestyle VC, and RRE Ventures. The company is currently headquartered in Brooklyn and invites everybody to stop by for a free Fi tennis ball.

Keep reading this honest Fi tracker review to learn more about the collar and its capabilities and see if it works for your pets.

How Fi Tracker Works

Fi tracker comes with a GPS module that tracks your dog 24/7 on the new LTE-M network, which allows you to be aware of his or her movement even when taken out by dog walkers and/or caretakers. Fi tracker is famous for its incredible battery life so you can basically put it on and forget about it for months.

It also allows you to create safe zones and receive notifications when your dog exits the perimeter. Since the collar works perfectly fine in all US states, you will receive instant escape notifications anywhere in the country. You can create as many safe zones as you want, which makes traveling with your pet much safer and easier.

Apart from tracking your dog, Fi tracker can help you keep your pet active and healthy by hitting his or her daily, weekly, and monthly step goal, comparing the score with other dogs, and monitoring activity levels when you are not there.

One of the most prominent features offered by Fi pet tracker is the Lost Dog Mode that switches to live location tracking to help you find your pet as quickly as possible. The Lost Dog Mode also activates the red pulsing LED light on the collar, which makes it easier to spot your pet in low visibility conditions or at night. Once your collar enters the Lost Dog Mode, Fi HQ will immediately be notified and the company’s 24/7 lost dog helpline will be at your disposal.

Fi Tracker Design

The Fi collar features a durable and sturdy design with the tracking module being held in place by a tough nylon band. Note that you should not rely solely on Fi tracker as a link to your dog’s leash even though it is able to handle even the most adventurous of pets. The collar is waterproof and can even withstand salt water. Furthermore, it is chew-proof so there should not be any problems in multi-pet households.

The band comes in yellow and gray, but note that the yellow version does not have an XL size. When it comes to Fi sizing, here is your definitive guide:

  • S – Neck <13” 
  • M – 13.5” – 16.5” 
  • L – 16″ – 22.5” 
  • XL – 22″ – 34.5” 

You should be able to fit two fingers between the collar and your dog’s neck for optimal comfort. In other words, the collar should feel snug but not too tight.

If the band gets damaged at any given point, you can replace it by simply unlocking the end links and separating it from the module. If the end links get damaged, you can contact the company’s customer support team at Monday to Friday 10 AM – 5 PM EST.

The Fi collar features an LED indicator light. Understanding different modes will help you use the product to its full potential:

  • Solid blue – Fully charged; 
  • Pulsing blue – Charging; 
  • Pulsing red – “Lost Dog” Mode; 
  • Pulsing green – Activated, restarting, reset, the firmware has recently been updated. 

Fi Tracker Technical Specification

This part of our Fi tracker review will focus on the collar’s technical characteristics and implemented technologies.

LTE-M Network

LTE-M is a low-power cellular network specifically designed for IoT devices. It provides dog owners with ultra-long battery life and extended cellular range.


Apart from using GPS and Wi-Fi, the collar can also utilize low-power Bluetooth connection to communicate with other devices like Fitbits, Airpods, and others.

Battery (Lithium-ion – 520mAh)

As we already mentioned in this Fi tracker review, battery life is one of the most impressive features of this collar. Depending on your usage, you can go up to 3 months without recharging the battery. The battery will last up to 2 months if your dog is constantly outside of your home (Wi-Fi & GPS/cellular mixed mode), up to 3 weeks if you are using GPS without Wi-Fi, and up to 2 days in the Lost Dog Mode (with 1-minute refresh).


The Fi collar is extremely resistant to damage caused by outside influences so if you own multiple pets, they will not be able to chew through each other’s collars. Furthermore, your dog will not be able to damage the module or the band no matter how adventurous he or she is.


Unlike many other tracking collars that are only water-resistant, Fi tracker is completely waterproof and can even withstand salt water without any damage or diminished performance. Its waterproof rating is IP-68, which means you can immerse it in up to 1.5m of water without any negative consequences.

The LTE-M network gives you 20-30% more coverage than your regular 3G/LTE networks. This means Fi will be able to track your pet in areas where 3G trackers simply do not work. Fi covers every state in the US

Fi Tracker App

The Fi app will show you your dog’s location in the primary view the moment you open the app. You can scroll the area by swiping across the map or zoom in/out by pinching and pulling your fingers together or apart. This is especially useful while setting up safe zones.

fi pet tracker smart phone app

The app is easy to use, with the first initial representing your current location and the photo of your dog representing where he or she is located. If you are together, the two icons will attach to each other. The app features the “Locator” and “Lost” buttons that point out your current location/where your dog was last recorded and activate the Lost Dog Mode, respectively.

The bottom of the screen is reserved for your dog’s activity and you can always swipe to view past activities. For more in-depth info, simply tap the steps count and toggle between Day, Week, and Month to track your pet’s progress.

Finally, the app allows you to access Fi’s live chat support during the team’s regular business hours.

Fi Tracker Features

Let us now go over some of the most prominent features provided by the Fi tracker and see what sets it apart from other pet tracking devices.

LTE-M Network

Using LTE-M instead or regular 3G/LTE networks enables Fi tracker to provide you with extended range and track your dog’s activity in areas where traditional pet trackers simply do not work.

Durable Design

The Fi collar comes with a tough nylon band that is completely dog-proof and easy to replace. The main module is also chew-proof and built to withstand even the unruliest of pets.

User-Friendly Mobile App

Fi tracker comes with its own app that is very easy to use thanks to its intuitive menus and general lack of unnecessary clutter.

Long-Lasting Battery

Thanks to its low-power network and Bluetooth connectivity, Fi tracker can last up to 3 months, depending on usage.


Fi tracker allows you to set up unlimited safe zones across the US, so you will always receive instant notifications the moment your pet leaves the perimeter.

Global Coverage

The Fi collar works in all the states and even covers some rural areas where regular 3G/LTE trackers cannot establish a viable connection.

Fi Coverage

As we already mentioned in this Fi tracker review, the unit works in any state in the US and can even track your dog in some of the rural areas that leave 3G/LTE trackers powerless and useless. However, you still need Internet access in order to view the readings on your Fi app.

How Much Does Fi Tracker Cost?

We should note that the collar is basically useless without a subscription since it will stop tracking your dog’s location the moment he or she leaves the Wi-Fi range of the home base. In other words, if you want to unlock GPS tracking, going with one of the subscription plans is a must. The Lost Dog Mode and live agent support are also only available to premium customers.

Once you purchase your Fi collar, you have a 30-day trial period during which you can return it for a full refund. The collar also comes with a full 1-year warranty.

Fi Pros & Cons

  • 1-year warranty 


  • Requires a subscription

Bottom Line

Fi tracker is a modern pet tracker primarily designed to find lost dogs and monitor their location, activity, and health on a regular basis. It allows you to set up safe zones and receive instant notifications when your pet leaves the predefined perimeter. The home base enables it to utilize Wi-Fi instead of GPS while your dog is in range in order to save battery. Speaking of battery, Fi tracker has one of the most impressive batteries on the market that can last for up to 3 months, depending on usage.

On the other hand, the collar is pretty much useless if you do not purchase one of the available subscription plans. Furthermore, the shortest plan includes a 1-year subscription so you do not have the option of going month-to-month and opting out if you so choose.

Bottom line, Fi tracker is an excellent pet tracker that will monitor your dog’s location and activity pretty much anywhere in the US with the only downside being that you have to purchase a subscription.

    I’ve had this collar for about a year and I feel very luke warm about it. Pros : the battery life and the light function. I have a black dog and at night it’s nice to be able to activate a light so I can see her in the yard. Cons: there’s a lot of bugs and when I contact support they have either forgotten to get back to me or asked me to trouble shoot myself by “walking around my house testing my blue tooth functionality and strength” etc. They have never once, not a single time, taken responsibility and said they would work on issues. Mainly, false notifications, late notifications or just simply no notifications. At least 4-5 times a week, sometimes 4-5 times a day, I get the message that GPS can not locate my dogs collar. I also get notifications at random times 3am, 6am, 9pm that my dog has left when she’s sleeping next to me. Sometimes we go about our day going in and out of the house and we get zero notifications about leaving the safe zone or I get those alarms hours later. Tech support shrugs all this off. So although having the collar gives me some peace of mind, it’s very little. I don’t have a lot of confidence in the system but I’m hoping if my dog ever escapes (and I get the notice 40 mins later) that the lost dog gps functionality will actually work and Ill have a chance of finding her. Something is better than nothing? The company is young so hopefully they improve support and work on issues over time. Good concept it just doesn’t execute. Also the collar logo fell off (it’s just glued on) and don’t ever use the collar to walk your dog or hold them because it easily breaks apart and doesn’t hold up under pressure.

    We’ve been disappointed with this. We were sold on the 2-month battery life and that’s a joke. More like 2-3 weeks. It also cracked beyond repair after about 3 months, and we DON’T use the collar to connect to a leash. Our dog wears a separate collar for her leash. The Fi is exclusively for her GPS. Thankfully, it was still under warranty, but the next time it happens, it might be out of warranty. We can notifications in the middle of the night when our dog is in bed, or when she’s in her crate mid-day that she’s both away from home and from her owner (not true), and frequent messages that the unit is offline. Major room for improvement.

  3. Geoffrey Stanley | December 10, 2019

    The thing I like most about this app is that it has its own app where you can track your dog’s movement easily and without confusion. I’m not good with tech so it’s really important that know what I’m doing and fi tracker app made it easy. Another thing I like is that is not state limited so I can use it even when I take my dog traveling. We went hiking when we were at my boyfriend’s parents in Colorado and the app worked all the way even when we were high up and without a strong signal. I feel safe knowing my Penny is well taken care of.

  4. Jose Ball | November 29, 2019

    I very satisfied with the tracker except for the collar which didn’t last that long. I have two dogs one of them being very active. He likes to chew everything most of all his brother’s collar. Every time we go out both of my dog get very excited and while Ben knows how to sit down and wait for the leash, Roger gets unbearable while he jumps up and down and keeps biting his brother’s collar. Long story short the collar is all chewed up and has to be replaced. I was hoping it could withstand more.

  5. Delbert Gomez | November 20, 2019

    This Fi tracker is the best thing that has happened to me! My buddy and I take long walks around to the lake almost every day. He loves jumping into the water even when it’s cold outside and this tracker seems to be handling it very well. For me the battery lasted more than a month and a half and gps work even in the remote areas where coverage is not that good. The app is easy to read and it has the lost dog mode which is immediately activated in case anything bad happens. I feel much better ever since my dog started wearing it.

  6. Tommie Mccoy | November 2, 2019

    I always wondered what would I do if Charlie, that’s my dog, would to run away when we were traveling. I would love to take him anywhere with me but I don’t know how he’ll react to new environments so I leave him with my mom and dad mostly. And it was tearing my heart. I did a little research and found that Fi Tracker enables whole country coverage in case you and your pet leave the state. I’ve recently bought it I was amazed by how long the battery lasts, I didn’t need to charge it yet and it has been almost a month. Finally, I was able to take Charlie on a road trip, we went to see my parents is Vioming for a test drive. I was tracking our movement on the app the whole time we were there. Couldn’t be happier!

  7. Chris Tashjian | October 28, 2019

    Certainly does not give me confidence in a product made to give us peace of mind.
    I would go with the alternatives if I could go back. Mine has had many issues with signals going in and out. Even in the middle of the night while our girl is stationary I receive dozens of notifications saying that the collar cannot be located.
    The support team is nearly unresponsive and entirely unhelpful. When they do respond, they say that it is normal.
    It will also randomly show us that she is almost a mile away from home and then revert right back. That coupled with its seeming inaccuracy makes us wonder if she really is lost or out.
    2 stars because the activity monitor is neat to track on her walks.

    • Erica | February 17, 2020

      We experience the same inconsistent monitoring issues and the same indifferent response from tech support. Good to know it’s not just on our end.

  8. Kim | October 27, 2019

    We have a rescue who is a major flight risk due to her background. The first collar we received fell off due to the base cracking. We received a second. The second cracked again. In between sending the cracked one back and receiving the new one, our dog went missing. If we do find her, we’ll definitely be using a different product.

  9. Michelle Kenneally | September 24, 2019

    Having just left the tracker company starting with a W…I can tell you that Fi is hands down a better product…
    I was used to charging every 2-3 months since doggo is a couch potato & Fi lives up to its word on that.
    The W company “improved” their product so now I would need to charge every 3 DAYS or so.
    Apples to apples Fi is just a better product…
    As long as the unit senses I am with my dog via the app, I do not get an alert when we leave the zone…As long as we leave together!! Very smart!!
    The other company alerted every single time I left the house with her in the car…(a lot)…
    I much prefer the billing to not be every month so I don’t need to think about it…
    Hopefully Fi can grab the lions share of the market & remember the people who helped grow the company…unlike the W company…Loyalty is important!

  10. Dorothy Stogner | June 28, 2019

    I was disappointed when I realized that buying a tracker without a subscription plan is almost pointless. I don’t mind paying extra for this feature but they should’ve made it more clear from the start. Can’t help but feeling tricked.

  11. Kevin Graham | June 4, 2019

    The battery’s life span and the Bluetooth connection are two of my favorite features when it comes to Fi Tracker. I’m able to connect to my phone even without a wifi signal. The only thing I would like to see them work on is the width of the collar strap for larger dogs. It would look better & seem more reliable.

  12. Leroy Armstrong | May 28, 2019

    Deciding on Fi Tracker made sense since I usually forget to charge the battery. The fact that I don’t need to do that for almost 3 months was what I was sold on. However, it’s not quite as advertised… In reality with GPS constantly turned on the battery lasts around 3 weeks. Other than that, everything else is as good as it sounds.

    • Carisa B Wilkey | February 16, 2020

      The collar is great! I hate how there’s no customer service number to call. I’m also don’t like how there’s no month to month subscription. And I’m especially pissed that these jerks charged me 2 times for the yearly subscription, once last month & then again today. WTH??? Unacceptable!!!

  13. Teresa Beck | May 17, 2019

    I take my dog to the beach every day so having a completely waterproof tracker which is also resistant to saltwater was a dream come true. We immediately took it out for a test ride and needless to say it still works like clockwork!

  14. Mark Glazer | May 4, 2019

    Besides the long-lasting battery and awesome features like GPS, Wi-Fi, and the Bluetooth connection, Fi tracker’s activity tracking feature turned out to be quite impressive. I’m able to see how many steps my dog made and what time he was active. I can use different types of graphs to showcase the data which can be set by the hour, day or month. You can even set your dog’s daily steps goal.

  15. Robert Hollingsworth | April 28, 2019

    This collar is indestructible! Every time we go out my, one of my dogs, Pupper, who is hyperactive, starts chewing on the other one’s leash and color. Many have gone to waste but this one remains almost without any damage. The tracker itself is useful and durable as expected but the color is want impressed me the most!

  16. Michael Sorensen | April 11, 2019

    I bought the thing without realizing I’d also have to pay more money to unlock some of the basic stuff I was promised with the collar. And to top it all off, I have to commit for a full year which is just insane.

  17. Mila Jackson | February 5, 2019

    This collar is literally indestructible. We have three dogs in our home and they still haven’t managed to chew through each other’s collars as they did with so many unfortunate models we had before. They can even take a bath in our local lake without any damage whatsoever. Couldn’t be happier with Fi and would recommend it to all dog parents out there.
