Description
A smart GPS tracker that shows where your pet is, right now. Unlike Bluetooth tags and AirTag, it has its own eSIM and GPS module inside, so it does not depend on other people's phones nearby and works at any distance - as long as there is a mobile network. In the application, you see a live route updated every few seconds, and the search function leads to the pet with an arrow and shows how many meters away it is. Separately, the tracker monitors activity: steps, play and rest time, calories burned - convenient for keeping your dog or cat in shape. The new version of the tracker additionally shows the pet’s approximate heart rate at rest and during exercise and changes in the usual range. This data helps you notice that your pet's routine has changed, but is not intended for diagnosis, treatment, or emergency monitoring. The body is lightweight (30 g) and protected according to the IP67 standard, so swimming and rain are not a problem for it. Charges on a wireless stand in a couple of hours. Attaches with a Velcro strap to any collar or harness.
Features
- Live search in real time: the pet's point on the map is updated approximately every 10 seconds, and the application leads to it with an arrow and shows the distance.
- No range limitation: it works via a mobile network with a built-in eSIM, and not via Bluetooth - you will find your pet in the next yard or outside the city.
- Pulse and activity: the sensor on the collar shows the approximate pulse at rest and during exercise - you see the dynamics and changes in your pet’s usual routine.
- Habitual range analysis: The app compares sensor readings and activity with your pet's normal readings and sends a push notification if there are noticeable changes.
- Activity monitoring: steps, active and quiet minutes, calories burned - helps keep your pet in shape and see if he has enough walks.
- Lightweight and unnoticeable: only 30 grams, the size of a finger battery, attached to any collar with a reliable Velcro strap.

What the app shows
The tracker is not a medical device, does not treat or make diagnoses - it shows activity, rest and approximate sensor indicators so that you can see changes in your pet’s usual routine.
Pulse and loadThe sensor shows the approximate heart rate at rest and during exercise. The application remembers the pet's usual range and notes noticeable changes.
Activity and restSteps, active minutes, sleep time. A noticeable drop in activity or a change in rest time helps to pay attention to your well-being in time.
Dynamics by weekYou can see not just one-off bursts, but a trend: the pet gradually began to move less, it takes longer to recover after a walk, and the night’s rest has changed.
🔔 Analyzes the usual rangeYou don't need to study charts every day. The application compares the indicators with the normal pet mode and sends notifications when noticeable changes occur - so that you pay attention to your well-being in a timely manner.
When to consult a veterinarian
If you receive a notification about a noticeable change in the usual range, this is a reason to take a closer look at your pet and, if necessary, show it to a doctor. The decision is always yours, here are the signs to look out for:
- Resting heart rate is consistently higher or lower than usual for your pet for several days in a row.
- Noticeable drop in activity — the pet began to walk and play less for no apparent reason.
- Sleeps much longer than usual or, conversely, is restless and cannot lie down.
- Long recovery after exercise — I used to get back to normal quickly, but now I don’t.
- Any of these changes along with changes in appetite, gait or habitual behavior.
Important: If there is a noticeable deterioration in health, unusual behavior or refusal of water, contact a veterinary clinic. The tracker is not intended for emergency monitoring.

The cat ran away - found it in 6 minutes
The cat ran out into the entrance and disappeared. I opened the application - I saw its point on the map in real time, the arrow led directly to the neighboring yard. Previously, I would have searched until night. Now I walk in peace.

The accuracy in the forest was surprising
I take the dog to the dacha, where he runs around the forest without a leash. The tracker shows the route with almost no delay and is updated every few seconds. Once I ran after a roe deer - I reached it along the arrow in about ten minutes.

Great, but needs to be charged every few days
It works as it should, it catches even outside the city. The only thing is that the charge lasts for several days, not for a month, so I charge it on weekends. But the stand is wireless, throw it and forget it. Activity counts - now I see that the dog really doesn’t walk much.

Activity is an unexpected bonus
I took it for the sake of searching, but got stuck on the statistics: steps, calories, how much I played and slept. The veterinarian told me to walk him more - now I can see the norm based on the numbers. The strap holds tightly and has never come off.

I survived the swim calmly
Labrador gets into every puddle and lake. I was worried about the electronics, but the IP67 did not let me down - it floats with the tracker, everything works. Lightweight, the dog doesn’t notice it at all.

Peace of mind for your pet
The main thing is that you no longer panic if you forgot to close the gate. I opened the phone, saw where the dog was, and went and got it. It can be set up in five minutes, the map is clear.
