GPS tracker for dogs & cats

Let 'em rip. No monthly fee.

Stop hovering. Open gate, escape artist, ten acres or the far side of the dog park, Zuumies puts them back on the map in seconds. $179, once. Ten years of cellular data already paid for. Nothing to cancel, because there's nothing to sign up for.

First 100 pay $149 and ship first. One email when we go live, nothing else.

Why we did it this way

Count how many things bill you every month. Now add your dog.

That was the moment this product existed. Streaming, storage, the car app, the doorbell, the vacuum, and then a $10 monthly fee to know where your own animal is. Enough.

A ten-year cellular plan costs us about $14 wholesale. So we buy it upfront, put it in the price, and never send you a bill. That's the whole trick. There's no catch, just a different business model.

It also means nobody can switch your tracker off. In August 2025 every Whistle device in America stopped working after the brand was acquired. The hardware was fine. The servers weren't.

The multi-pet problem

Two dogs shouldn't cost twice the rent.

Subscription trackers bill per device, so every animal multiplies the monthly fee forever. A second Zuumies is just a second $179, once, and both live in one app under one account.

The point of all this

Let 'em rip.

A tracker isn't really about the tracking. It's about the leash you don't clip, the field you let them cross, the ten minutes you don't spend shouting a name down the street.

Knowing you can find them in seconds is what lets you stop hovering. That's the actual product. The hardware is just how it gets delivered.

In development

Zuumies Heat

A dog can be in trouble inside a car in ten minutes, and on a walk in twenty. Neither one feels like an emergency to the person until it already is.

Zuumies Heat sits on the collar and watches two things: the air temperature around your dog, and whether they are moving. When the heat crosses the threshold for their breed and size, your phone gets a notification. Not an entry in a log you have to remember to open. A notification.

ON A WALK

The air climbs faster than you notice

Especially with a dog who will not stop before you do. You get told to turn back while turning back is still enough.

LEFT IN A CAR

You meant to be five minutes

The queue was long, the AC cut out, someone started talking to you. The alert reaches you while it still matters.

14%of heat-related illness cases in dogs end in death

Figures from Hall et al., Scientific Reports (2020), a study of 905,543 dogs under UK veterinary care.

Two things we will not pretend. This does not read your dog's core body temperature, because no collar sensor can do that honestly. And it is not a reason to leave a dog in a car. Nothing makes that safe. It is a safety net for the times something goes wrong anyway.

Same rule as everything else we make. Buy it once.

The Forever Guarantee

If we ever shut down, we'll open-source the server.

We're asking you to trust that something you buy once still works in ten years. That deserves scepticism. Whistle owners learned the hard way.

So, in writing: if Zuumies ever winds down, we publish the device protocol and open-source the backend so your tracker keeps working without us. We will not brick hardware you paid for.

The honest fine print: "ten years of included data" means 500 MB per device, which is normal use for a decade with room spare. Exhaust it and a top-up is $10. We'd rather give you the real number than say "unlimited" and hope you skip the terms.

Launching winter 2026

Ten years of data in the box. Geofencing included. Nothing to cancel, because there is nothing to sign up for.

Get $30 off and first shipment

The first 100 on the list pay $149 and ship before anyone else. No spam, one email when we go live.

Price shown is the intended launch price. Final specifications are being verified with our manufacturer and will be published in full before we take a single order.

The tracker

One for dogs. One for cats. Neither has a bill.

Zuumies fits any collar and takes the knocks a dog gives it. Zuumies Mini weighs 19 grams, light enough for a cat's breakaway collar. Both are IP67, both track live every ten seconds outdoors, and both come with ten years of data already paid for.

The tracker

Zuumies or Zuumies Mini, with ten years of cellular data already paid for.

Two silicone straps

Small and large, so it fits whatever collar they wear.

Charger

Charging base and USB cable. Two hours to full.

What it does

Everything the expensive ones do.

Live tracking

Location every ten seconds outdoors while you are actively looking. GPS and GLONASS, warm fix in about two seconds.

Smart geofencing

Draw safe zones around home, the yard, anywhere. Alert the moment they cross the line.

Home Wi-Fi and beacon

Recognises your home network and drops into low power, which is what preserves the battery. Tells you the moment they leave.

Activity monitoring

Daily movement and rest, so you can see whether they are getting enough exercise or slowing down.

Location history

Twenty-four hours of history in the app. Where they went, and when.

No-motion and low-battery alerts

Warned before the tracker dies, and warned if it stops moving when it should not.

Certification

Tested, certified, cleared to ship.

FCCCEPTCRB AT&TVERIZONIP67 UN38.3MSDSRoHS REACHSARAIR / SEA TRANSPORT

AT&T and Verizon carrier certification matters more than it sounds. It means the device is approved to run on the networks most of the country actually uses.

Sizing

Fits cats, fits mastiffs.

CATS & SMALL DOGS

MEDIUM & LARGE DOGS

Zuumies, 800 mAh

Bigger cell, longer runtime, leash attachment. Also used on horses and goats.

MULTI-PET

One app, one account

Add as many as you like. There's no per-device fee to add another.

One tracker. One payment. Ten years.

The app

Free, obviously.

There's no premium tier, no paywalled feature, no "upgrade to see history." You bought the tracker; the app is how you use it. iOS and Android, and every pet you own lives in the same account.

It knows the difference between at home and out. When your pet is inside your Wi-Fi, the app drops the tracker into low power. When they leave, it wakes up and tells you.

Every pet, one account

Add as many as you have. The billing screen exists only to show you there is nothing on it.

What it won't do

The honest list.

Work without cell coverage

LTE-M reaches further into fringe areas than a phone, but it can't report from nowhere. Genuinely off-grid? Buy a radio tracker instead.

Nag you to upgrade

There's no paid tier to sell you, so the app has no reason to interrupt you.

Sell your location data

Your pet's location is your data. We don't broker it, and US customer data stays on US servers.

Straight answers

Questions worth asking.

Is it really no subscription?

Really. We buy a ten-year prepaid cellular plan at wholesale and include it in the $179. No tier, no renewal, no card on file. The only cost that can ever arise is a $10 top-up if you exhaust 500 MB.

Does it need cell coverage?

Yes, and we'd rather say so plainly. LTE-M penetrates further than standard LTE but cannot report where there's no coverage at all.

How long does the battery last?

The 800 mAh cell is rated at 5 to 7 days, and the home Wi-Fi power-saving mode extends that. We publish tested numbers, not best-case ones, so the final figure lands here before we take orders.

What if I lose the tracker itself?

A replacement is $179 with its own ten years of data. No reactivation fee, because there's nothing to reactivate.
