All 7 pet gps trackers, ranked
Ranked by test scores, minus how common and serious the complaints are. How we rank
#1
Fi
$$GPS + cellularScore 3.9/5
15%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)Small sample (about 285 ratings); the listing pools sizes and colors.A Wirecutter top pick and PCMag's 'most durable' tracker: slim, stainless steel and nearly as fast as Tractive, with long battery life thanks to its charging base. But it only fits Fi-compatible collars, goes offline more often than Tractive in Wirecutter's tests, and works best with the app running in the background.
Subscription: Required Fi membership in 6-month, 1-year or 2-year terms (Wirecutter); Fi says every membership includes the Series 3+ collar
Top complaints
- Needs its own collar, which can rattleMentioned often
It attaches only to collars with Fi's proprietary endlinks. Wirecutter says some users, including one long-term tester, complain about the metal endlinks clicking or rattling.
- Goes offline; zigzag pathsMentioned often
Wirecutter saw the tracker go offline or fail to connect more often than Tractive's, and its live path sometimes zigzagged through buildings. It also works better if the app stays open in the background.
- Mixed accuracy and battery for ownersMentioned often
Amazon's review summary says accuracy and durability are mixed, and some owners need to charge every 5 to 6 days while others report phenomenal battery life. Some find it too expensive for what it does.
What owners love
- Fast, sharp tracking in a small package
Wirecutter measured a 16-second average connection to Lost Mode, just behind Tractive, with great accuracy. It weighed about 1 ounce on Wirecutter's scale.
- Tough and waterproof
It's IP68 plus IP66K for high-pressure water (Wirecutter), and PCMag names it the most durable pick. PCMag's Series 3 review notes the stainless steel case.
- Long battery thanks to the base
Its charging base and Bluetooth/Wi-Fi handoff saves power: it tied Tractive at 71% after 18 walks (Wirecutter). Fi claims up to 3 months per charge.
Skip it if…- You want to keep your dog's current collar
- You won't leave the Fi app running in the background
- You live where cell coverage is patchy
Good for- A slim, tough tracker for active or swimming dogs
- Small dogs (Fi's size chart starts at 5 lb)
- Activity and behavior insights

71% after 18 walks (Wirecutter); Fi claims up to 3 months. Some Amazon owners charge every 5 to 6 days. - App & alerts3.5
Why 3.5?
PCMag calls Fi's app excellent, but Wirecutter found it glitchy at times, and it works best when left running in the background. - Ongoing cost3.0
Why 3.0?
Membership required; Wirecutter says costs are roughly comparable in year one, but Tractive is consistently cheaper from the second year. - Fit & durability4.5
Why 4.5?
Stainless steel, IP68 and IP66K, and PCMag's most durable pick; it's tied to Fi-compatible collars, which can rattle.
What experts say
- Wirecutter (NYT): Top pick for dogs that 'packs a lot into a small device', but you can't use it with just any collar.
- PCMag: Most Durable pick (guide updated 2026-09-22). PCMag's Series 3 review (4.0, Editors' Choice) praised the streamlined design, but escape alerts took three to five minutes.
#2
Apple
$Bluetooth tagScore 3.5/5
8%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)General-purpose item-tracker listing; most ratings aren't about pet use.A cheap, excellent item finder that PCMag lists as its iPhone-friendly Bluetooth option in its pet tracker guide. But it's not a real-time pet tracker: it updates only when an iPhone passes nearby, Wirecutter found AirTag updates far less frequent than any GPS tracker, and Apple says it isn't meant for tracking pets.
Subscription: None mentioned in PCMag's review; it locates through nearby Apple devices (Find My network) and needs an iPhone
Top complaints
- No real-time trackingVery common
Wirecutter's AirTag test updated the dog's location far less often than any GPS tracker, only when the dog came within Bluetooth range of an iPhone, and sometimes not at all. PCMag says the location is only as accurate as the last iPhone that passed by.
- Not designed for petsMentioned often
PCMag notes Apple clearly states the AirTag is meant to find lost items, not keep tabs on family, friends or pets. Wirecutter dismissed general-purpose Bluetooth trackers for finding a pet on the run.
- iPhone only; needs a holderMentioned often
PCMag lists no Android support and no way to attach it without accessories. Amazon owners report mixed connectivity, with some saying it won't pair with their iPhone.
What owners love
- Precise close-range finding
Precision Finding now works from 1.5 times farther away and from an Apple Watch, and the speaker is louder (PCMag). Amazon owners praise the accurate tracking and Precision Finding.
- Year-long, replaceable battery
It takes a standard CR2032 coin cell that Apple says lasts about a year, and it's IP67 water-resistant (PCMag).
- Cheap and easy
It costs $29 (PCMag), and Amazon owners find it easy to set up and use.
Skip it if…- Your dog runs off in rural or low-traffic areas
- You use Android
- You need escape alerts or live tracking
Good for- Indoor cats or dogs that hide nearby
- iPhone owners on a tight budget
- A backup to a GPS tracker

Tractive
$$GPS + cellularScore 3.7/5
24%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)This listing bundles a 6-month subscription and pools color variants.Wirecutter's top dog pick for the most consistently accurate live tracking and the fastest GPS connection it measured. But PCMag got four to eight false escape alerts a day and poor battery life when Wi-Fi power saving wouldn't connect, and about 1 in 4 Amazon ratings are 1 or 2 stars.
Subscription: Required, prepaid: $120 for 1 year, $168 for 2 years or $300 for 5 years (PCMag); Wirecutter says Tractive has no monthly option
Top complaints
- False escape alertsVery common
PCMag got four to eight false 'left the safe zone' alerts per day while the dog was napping nearby; Tractive told PCMag the system is tuned to err on the side of sensitivity. A Wirecutter long-term tester also had false escape alerts, while Wirecutter's own testing twice missed real exits.
- Battery life varies a lotVery common
PCMag couldn't get the Wi-Fi Power Saving Zone to work after weeks of troubleshooting, so battery life suffered. Amazon's review summary says some owners get two weeks per charge and others only one.
- Bulky, with mixed durabilityMentioned often
Wirecutter calls it pretty clunky next to Fi's trackers, and PCMag says it feels about twice as large as the Fi Mini. Amazon's summary says durability is mixed, with some units breaking within 60 days.
What owners love
- Most accurate live tracking
Wirecutter found it gave the most consistently accurate live-tracking updates of any device it tested, usually off by only a few yards, and it connected in about 13 seconds on average, faster than every other tracker.
- Fast escape alerts
PCMag's real escape alerts all arrived within 90 seconds, most closer to 60, faster than the Fi Mini's.
- Lights, waterproofing and USB-C
Wirecutter likes the bright LED strips, IP68 waterproofing that held up in rain and snow, and the built-in USB-C port. Amazon owners call the app easy to use.
Skip it if…- You have a small dog and want a slim tracker
- Frequent false alerts would make you ignore them
- You want to pay month to month
Good for- Following a runaway dog in near real time
- Medium and large dogs (9 lb and up)
- Lowest total cost after the first year
- Very large dogs (over 70–80 lb): the bigger Dog 6 XL had by far the best battery life in Wirecutter's tests

Why 3.0?
An intuitive map (Wirecutter) and fast escape alerts, but four to eight false alerts a day for PCMag and occasional glitches for Wirecutter. - Ongoing cost4.0
Why 4.0?
A cheap device plus $120 a year (PCMag). Wirecutter has seen Tractive consistently cost less overall once you reach the second year, but it requires at least a one-year prepay. - Fit & durability3.5
Why 3.5?
IP68, lights and a secure fit on most collars (Wirecutter), but it's bulky, and Amazon owners are mixed on durability.
What experts say
- Wirecutter (NYT): Top pick for dogs (updated 2026-05-11). It has the best accuracy, connection speed and battery life, but it's bulky and the app can be glitchy.
- PCMag: The hardware is a delight, but Wi-Fi pairing failures and frequent false escape alerts keep PCMag from fully recommending it. PCMag prefers the Fi Mini.

Tractive
$$GPS + cellularScore 3.5/5
24%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)Small sample (about 220 ratings); the listing pools colors.Wirecutter's best tracker for cats, with the same fast, precise tracking as Tractive's dog model and an excellent history map of where your cat roams. But its battery died after 5.5 days in testing, it's still bulky for a cat, and a buckle tab broke during fitting.
Subscription: Required: 1-, 2- or 5-year plans (Wirecutter)
Top complaints
- Short battery lifeMentioned often
Wirecutter's unit was completely drained after 5.5 days on an active indoor-outdoor cat, the shortest of its picks. The Fi Mini For Cats still had about 30% left after the same time. Tractive's Amazon listing claims up to 7 days.
- Bulky, with flimsy plasticMentioned often
Wirecutter says it's curved to fit a cat's neck but still pretty bulky, and one buckle-release tab broke off while fitting the collar.
- Proprietary chargerOccasional
The charging cord uses a unique magnetic attachment that won't work with other devices (Wirecutter).
What owners love
- Fast, precise tracking
Wirecutter found it had the same fast, reliable connection and live-tracking accuracy as the Tractive Dog 6.
- Excellent history feature
The app shows your cat's paths over a custom time frame, with an optional heat map and territory outline (Wirecutter).
- Lights to find a hiding cat
Two light strips help you spot a cat in a tree or bushes, though Wirecutter says the jingle may be too quiet outdoors. It comes with its own cat collar.
Skip it if…- You don't want to charge every few days
- Your cat won't tolerate a bulky collar
- Your cat stays indoors (GPS struggles indoors)
Good for- Indoor-outdoor cats
- Seeing where your cat roams (heat map and territory)

Fi
$$GPS + cellularScore 3.5/5
37%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)Small sample (about 170 ratings); the listing includes a 1-month membership.PCMag's best overall pet tracker and Wirecutter's runner-up: the smallest, lightest tracker either tested, and it clips onto most collars. But about a third of its small number of Amazon ratings are 1 star, with owners saying it falls off the collar or its GPS often doesn't work.
Subscription: Required and bundled with the hardware: $99 with 6 months of service, $189 with 12 months (about $15.75/mo) or $339 for two years (PCMag)
Top complaints
- Falls off or loses GPS for some ownersVery common
Amazon's review summary says the device won't stay on the collar for some owners and that GPS often doesn't work for others; reliability and value are mixed. About 37% of ratings are 1 or 2 stars.
- Inconsistent alerts and occasional dropoutsMentioned often
PCMag's escape alerts arrived anywhere from one to nine minutes after the dog left the safe zone, and small safe zones are hard to set. Wirecutter saw it go offline a few times and hiccup when starting live tracking.
- Battery depends on setup; no lightMentioned often
Amazon owners report battery life from fantastic to a couple of days. Wirecutter says it likely runs low much faster without a Fi base and has no light. It's plastic, so it may be less durable than the Series 3+.
What owners love
- Tiny and fits most collars
At 0.56 ounce, it's the smallest and lightest tracker Wirecutter tested. It attaches to most collars or harnesses with silicone straps or cases, and Wirecutter's never budged over several months.
- Long battery for its size
It lasted more than four weeks per charge in PCMag's testing (full to 75% in 10 days). Wirecutter measured 68% after 18 walks versus 71% for the Series 3+.
- Responsive Lost Mode and a polished app
PCMag found Lost Mode location updates speedy and reliable, liked the heat map and walk replays, and found activity and sleep stats accurate. Amazon owners praise its accurate real-time tracking.
Skip it if…- You have a rough, chewing or very active dog
- You want a built-in light
- You need instant escape alerts
Good for- Small and medium dogs
- Keeping your dog's existing collar or harness
- Long battery between charges

What experts say
- PCMag: Best Overall GPS Pet Tracker and Editors' Choice (4.0, guide updated 2026-09-22): long battery, compact and reliable, though its eating and drinking data was inaccurate.
- Wirecutter (NYT): Runner-up for dogs: nearly as fast and accurate as the Series 3+ and fits most collars, but its battery doesn't last as long. The Fi Mini For Cats went offline several times in its cat test.

Halo
$$$GPS collar with fenceScore 3.0/5
Amazon 1–2 star share
not available
A virtual-fence collar rather than a simple tracker: GearJunkie found the fifth generation's GPS locked on and more reliable than earlier models. But it costs $599 list plus a required plan, it needs charging every day or two, and PCMag (testing the Collar 4) says it only works if you put in extensive training.
Subscription: Required: plans from $9.99/mo (Halo); for the Halo Collar 4, PCMag listed Bronze $9.99/mo (5 fences), Silver $14.99/mo (20 fences) and Gold $19.99/mo (unlimited)
Top complaints
- Expensive, with a required planVery common
GearJunkie reviewed it at $599 and says the price stings; Halo's site listed it at $445 on sale. PCMag lists 'expensive, with costly data service required' as the Halo Collar 4's top con.
- Only works with extensive trainingMentioned often
PCMag says training is an absolute necessity: Halo's full program takes 21 days, and PCMag's tester never got to the point of fully trusting the Collar 4's fences. Fences can't overlap.
- Frequent charging; slow app for correctionsMentioned often
Battery is up to 40 hours per GearJunkie (Halo says up to 48). GearJunkie says that by the time the app loads and you select a correction, the moment has often passed. On the Collar 4, PCMag got no app notification when the collar left the fence.
What owners love
- More reliable GPS
GearJunkie says a dual-chip design cuts 'lost connection' alerts and the GPS seemed locked on, with 20 GPS updates per second. PCMag praised the Collar 4's accurate location features.
- Better battery and fast charging
GearJunkie's lasted through multiple long days, which past models didn't, and a 1-hour charge gets it over half full.
- Strong app and feedback options
PCMag calls the Collar 4's companion app excellent, with plenty of feedback options from sounds to static and an IP67 build. GearJunkie likes the positive cues and activity tracking.
Skip it if…- You only need to find a lost dog
- You don't want to charge every day or two
- You want to avoid a monthly fee
Good for- Keeping a dog in an unfenced yard or property
- Owners willing to do weeks of training
- Tracking and training in one collar

Why 3.5?
Fits 8 to 30.5 inch necks with an improved fit system (GearJunkie) and an IP67 build; the Collar 4 weighed a hefty 6.55 ounces (PCMag).
What experts say
- GearJunkie: 8.8/10: a meaningful upgrade with longer battery life, faster GPS and better connectivity. It's still expensive, but GearJunkie thinks it's worth the price.
- PCMag: Best GPS Dog Fence pick is still the Halo Collar 4 (4.0, guide updated 2026-09-22). For reliable escape alerts, PCMag suggests a real fence plus a dedicated tracker.

of Amazon ratings are 1–2 stars
(checked 2026-10-10)Small sample (about 482 ratings). The listing is the SpotOn Omni collar (medium), and sizes appear to share ratings; PCMag's review may cover an earlier SpotOn version.PCMag's pick for large properties: accurate GPS fencing with overlapping fences and an off-grid mode, and no subscription unless you want live tracking. But it costs $999, weighs half a pound, is rated for only 26 hours of battery, and needs extensive training.
Subscription: Optional, needed only for live location tracking: $9.95/mo, $95.40/yr or $142.80 for two years (PCMag); the fence works without it
Top complaints
- Very expensiveVery common
At $999 it's one of the most expensive options in the category (PCMag). Amazon owners are mixed on value for money.
- Mixed accuracy, battery, and unwanted correctionsMentioned often
Amazon's review summary says some owners find GPS amazingly precise while others say it's not accurate, some say the battery doesn't last a full day, and some report their dogs getting corrected while inside the boundary. PCMag once got an out-of-fence warning while the collar sat on a desk.
- Training and big fences requiredMentioned often
PCMag says extensive training is required, fences must be about half an acre at minimum, and GPS is unreliable under a roof, so you need a home zone or must remove the collar indoors.
What owners love
- Accurate fencing, no required plan
PCMag praises the accurate GPS performance, overlapping virtual fences and off-grid mode, and the fence doesn't require a subscription.
- Dogs learn boundaries quickly
Amazon owners say it saved them from building a fence, that dogs learn the boundaries quickly, and that it gives them peace of mind.
- Frequent updates when tracking
With the optional plan, the app updates your dog's location every six seconds after it leaves the fence; the collar is IP67 and safe for swimming (PCMag).
Skip it if…- Your yard is under about half an acre
- Your dog is under 15 lb
- You won't invest in training

What experts say
- PCMag: Best Virtual Fence for Large Properties (4.0, guide updated 2026-09-22). The cons are the price, the training required, limited feedback sounds, and a subscription for real-time tracking.
