GPS Pet Trackers: AirTag vs. Tractive vs. Fi — an Honest Comparison
Last verified: August 2026
If your dog or cat is a wanderer, a tracker can save your heart. But an AirTag and a real GPS tracker are not the same thing — here's the honest difference, and what each actually costs.
About pet trackers
An Apple AirTag is tempting because it's cheap and needs no monthly fee, but it has no GPS inside. It finds itself by pinging off other people's iPhones nearby. In a crowded city that works surprisingly well; out here in Portage County, on a country road or in the woods, there may be no iPhones around for hours — so an AirTag can leave you with no location at all when it matters most. Apple itself says AirTags are for items, not pets.
Tractive and Fi are real GPS trackers built for pets. They use satellite GPS plus a cellular signal to report a live location almost anywhere there's cell coverage, which is why they need a paid subscription. Tractive runs roughly $6 a month on a yearly plan (about $13 month-to-month), and its premium plan is around $8.50 a month yearly. Fi is a rugged GPS collar; after the membership bundled with it runs out, plans are about $189 a year (or $99 for six months), plus a one-time $20 activation fee.
The honest bottom line: if you truly need to find a pet that gets loose, buy a real GPS tracker and accept the small monthly cost. An AirTag is fine for a slow-moving indoor cat you just want to locate in the house — but it is not a safety net for a runner.

Common Questions
1 Why isn't an AirTag good enough for my dog?
- An AirTag has no GPS — it relies on nearby iPhones to report where it is.
- In rural areas and woods with few phones around, updates can be hours apart or never arrive.
- It can't send you a live, moving location the way a real tracker can.
- If a dog chews the tag, the small battery is a choking hazard — use a secured holder.
- For a real runner, that's too big a gap; choose a true GPS tracker instead.
2 How do Tractive and Fi actually work?
- Both clip to or build into the collar and use GPS plus a cell signal to report location.
- You watch your pet live on an app on your phone, almost anywhere there's coverage.
- You draw safe zones (your yard, the house) and get an alert if your pet leaves.
- They track activity and sleep too, which vets sometimes find useful.
- Because they use a cell signal, they require a paid subscription to work.
3 What will it really cost me?
- Tractive's tracker is inexpensive up front; the subscription is about $6 a month on a yearly plan (around $13 month-to-month).
- Tractive's premium plan is roughly $8.50 a month when paid yearly.
- Fi's collar comes with some membership included; after that, plans run about $189 a year or $99 for six months.
- Fi also charges a one-time $20 activation fee.
- Longer prepaid plans lower the monthly cost for both.
4 Which should I choose?
- For cats and small dogs, Tractive's lightweight tracker is a popular, affordable pick.
- For a strong, escape-artist dog, Fi's rugged collar and long battery are well suited.
- Check that you have decent cell coverage where your pet roams — that's what these depend on.
- Consider battery life; both last days between charges, but heavy tracking drains faster.
- Bring me the two you're weighing and I'll help you set up whichever you pick.
