Smart GPS tracker with wellness sensor (SIM)

Our Jack Russell has slipped under the fence at the country house more than once. Instead of panicking and running down the road, I just opened the app - turned out he was over at the neighbor's place, nowhere near traffic. Knowing which direction to walk instead of guessing cut the stress in half.

For a large dog, the device body is small, and the buttons and collar attachment don't get in the way.

My cat had wandered a couple of yards over, and I just followed the on-screen arrow straight to her. Simple and accurate.

I like that the app shows the exact meters to the dog, so I don't have to guess which entrance she's at.

It lay in a puddle after the rain all day and still works perfectly. Waterproofing is top-notch.

The arrow is a lifesaver when the dog hides in tall grass. You just walk straight towards it.

It's convenient that one tracker works for both a dog and a cat. We swapped it between two collars.

The walking route is shown as a live trail, making it easy to see later where the cat turned off.

The app compares activity to the norm. It makes tracking health very convenient.

The main advantage over AirTags here is independence. The signal goes over cellular networks without any issues.

After surgery, we walk carefully. By monitoring rest time, I can see that the dog isn't being overexerted.

It showed that the cat is burning very few calories. We had to switch him to diet food.

Notifications arrive on the phone quickly, with no delays.

I liked that the tracker doesn't lose its usefulness over long distances, as long as there is a network.

I check the heart rate after a run not as a diagnosis, but as a gauge for workout intensity.

The live route literally draws lines showing where the cat goes. It's really cool.

It's so light the dog doesn't even notice it on his collar.

Felix went missing around the holiday houses, an area where Bluetooth tags had never worked for us since almost nobody else is ever around. This one pulled his location straight off the cellular network instead, and we tracked him down behind one of the sheds. Would buy again without a second thought.

Turned out she'd only gone about 20 meters, but I'd never have known which direction without the search-mode arrow pointing the way.

The cat roams freely while I watch her on the map. Position updates are very fast, it's a literal live feed.

The eSIM was a lifesaver outside the city where AirTags used to be useless. Setting up the data plan took longer than expected.

Now I track my Labrador's steps. The app shows when he hasn't moved much and it's time for a walk.

I liked that it doesn't require someone else's phone nearby. It works entirely on its own.

I like watching the distance count down in meters while I walk toward him behind the arrow - takes the guesswork out of it.

Bought two for two dogs. They hold a charge excellently and never lose connection.

The rest counter showed that our old beagle sleeps more after long weekend walks.

I check the resting heart rate in the morning; it’s noticeable when the cat was nervous after we had guests over.

Our cat usually has a calm rhythm, but the app noticed an unusually active evening.

Rainy fall, and the tracker keeps working hard without anything happening to it.

I liked the comparison with my pet’s normal range; the app doesn’t just show dry numbers.

A push notification about reduced activity came after a lazy day for our dachshund. Useful, but the notification text is too generic.

After using an AirTag, the difference is obvious: the tracker showed the route outside the city, where there are hardly any people.

I’d buy it again without question.

The heart rate after running looks roughly logical, useful for keeping track of the routine. I wish there were an explanation of what counts as a sudden change.

On a walk, the dot on the map moved almost right behind the dog, and I found him by the pond.

The well-being sensor is awesome. I can see my pug’s sleep trends.

Bruno is our beagle, and this was already his third escape chasing some scent or other. This time I could see his position by the canal and headed that way on foot while my husband drove around from the other side. We got to him fast, and the collar came through a puddle crossing without a scratch. Docking one star only because the zone-exit alert took a bit longer to arrive than I'd have liked.

The weight is fine for a cat; he sniffed it for the first ten minutes, then forgot about the device.

I check the heart rate under load when we run. Everything’s OK, the readings are stable.

My cat goes on nighttime outings, and now in the morning I can see where he wandered around the neighborhood.

The steps in the app motivate me to walk longer with my dachshund, and the chart is clear.

Took all of five minutes to track him down - he'd wandered into the yard next door.

We bought it for a beagle puppy named Milo; he’s interested in everything and suddenly speeds up on walks. Over two weeks we tested real-time search several times: the map didn’t freeze, and the activity readings later showed how much he’d run around. A very successful thing for our routine.

A push notification came when the cat had moved less than usual. Turned out she was just sleeping in the closet.

We got caught in heavy rain, the inside of the body stayed dry, and the app kept showing the dog.

Now I feel calm when the dog is walking in the yard.

It showed that my dog’s resting heart rate had jumped. We went to the vet, and it turned out to be a minor inflammation.

A notification about a change in activity came after a lazy day for our Labrador; it’s convenient for keeping track of his routine.

I attached it to the collar strap; it holds firmly and doesn’t fall off.

If the cat sleeps more than usual, it sends a push notification. A genuinely useful feature.

The walking route is shown in detail, my wife can later see where we went. Minus: the map sometimes doesn't load immediately.

After swimming in the lake, the tracker didn't shut off; I just wiped the casing with a towel.

In the app, you can see when the dog is playing and when it's just lying down. For our young Shepherd, this turned out to be more useful than I thought: after we moved, her routine got messed up, and by looking at the rest graph, we quickly realized she needed calmer walks in the evening.

The app is straightforward, everything is visual—graphs and maps. No unnecessary hassle.

Visibility in the park was bad that evening, and honestly the arrow got me to him faster than yelling his name ever did.

Convenient to track calories. My Beagle gained a little weight, and now we can monitor his activity levels.

Attached it to my Pug's collar, the weight is barely noticeable, he runs around as usual.

After a regular walk, I see not just a location dot, but how much the cat actually moved.

Followed the arrow straight to him in the park and it worked, though the distance reading jittered around a bit along the way.

Charges quickly, the battery lasts for a couple of days of active walks.

Bought it for our Maine Coon, he took to the tracker calmly. The only thing is the app occasionally asks you to log in again.

Notifications are panic-free, they simply show that the usual range has changed.

The cat jumped into wet grass and puddles, the tracker survived the walk without any issues.

The tracker handled swimming in the sea just fine. Solidly built.

With the eSIM, I didn't have to buy a separate card; we just turned it on and paired it with the app.

I have a Wirehaired Pointer, and on a hunt, the dog can run very far in search of game. I used to constantly worry about losing him in the woods. This Fernpaw gadget has been a game changer. It doesn't rely on having other people with phones nearby. The built-in SIM card catches the network and shows his location on the map every few seconds. I can see where the dog is during the hunt and how much he has run. The heart rate feature is also interesting; you can see how much he exerts himself while running.

It works even outside the city where mobile reception is barely there.

Our Spitz doesn't mind the tracker on his collar; it's lightweight and doesn't dangle.

Nora is our Husky, and she'll chase a scent into the woods without a second thought. We've used the tracker nearly daily for a month, and the one time she vanished near the field, the app's arrow got us within a few meters of her - watching that distance count down as we walked was oddly reassuring. Glad we bought it.

There's a gap in our fence that our Terrier treats as an open invitation to the woods behind the house. AirTags were useless out there since barely anyone else's phone ever comes near. This one's different - the dot on the map keeps updating every couple of seconds, and I just walk toward wherever it stops, usually the bushes. Five rescues in a month so far. Recommend it if your dog has any escape-artist tendencies.

Tested it in the neighboring district: the signal went through the cellular network, distance wasn't an issue.

I bought it for the GPS, but ended up getting a fitness tracker for my dog as a bonus.

Minor remark: the app needs a couple of seconds to load at startup, but after that it runs smoothly.

I like that it isn't reliant on nearby people having their phones; this is crucial for the village.

Stays on the cat fine, the weight is barely an issue. The clip could snap a bit quieter, though.

The price is definitely not low, but for that kind of independence from Bluetooth, it’s worth it.

I liked the activity charts; you can see how much the dog is actually resting.

After the rain, the tracker worked as usual, but the rubber charging cover is inconvenient to lift with a fingernail.

A small and neat tag. It’s not heavy for the dog to wear.

From the activity data, I noticed that the cat started playing less in the evening. It’s a shame the weekly charts are a bit too small.

It shows changes in the dog’s usual rhythm. We noticed that he started tossing and turning at night.

We swam in a lake and the tracker didn’t break; water isn’t a problem for it.

The tracker really doesn’t depend on other people’s iPhones. It works independently.

The map updated frequently when the puppy ran off after a cyclist, and we caught up with him calmly.

On a run with my border collie, the app showed the rise in heart rate and activity; everything was clear and easy to see.

I don’t treat the heart rate as medical data, but after active play I can see a clear trend.

Push notifications came through when the cat became less active than usual.

Our female retriever swam in the canal, and the tracker stayed connected; that was the main thing.

Perfect for cats. It attaches easily and doesn’t get in the way of their movement.

I checked it after the rain: the charging port was dry, the case cleaned quickly, and everything works.

The map updates are frequent; you don’t have to wait a minute at a time, which is reassuring.

I check the calories after playing fetch; it’s become easier to keep my corgi’s weight under control.
