If you already use Life360 for your family, is it worth adding your dog too? An honest comparison of Life360, Fi, and Tractive for real-time pet GPS tracking.
Life360 built its reputation as a family location-sharing app long before it touched pet tracking. But in 2026, it launched a genuine hardware GPS tracker for dogs and cats, and if you’re one of the roughly 55 million people already using Life360 for your family, the pitch is obvious: why juggle a second app just for your dog?
That’s a fair question, and the honest answer depends on what you actually need. Let’s compare all three head-to-head.
The Core Difference: Standalone vs. Family Ecosystem
Fi and Tractive are both built exclusively around pet tracking — the app, the features, and the whole design are focused on one job. Life360 takes a completely different approach: your dog is added to the same “Circle” as your family members, showing up on the same map as your kids, your partner, and your car. This isn’t a minor UI detail — it genuinely changes who’s likely to actually check the app regularly, since your whole household is already looking at it for other reasons.
Side-by-Side Comparison
| Feature | Fi | Tractive | Life360 |
|---|---|---|---|
| Device price | $129 (promos may lower it) | $79 (DOG 6) | $49.99 |
| Subscription required | Yes, prepaid: $99/6 mo, $189/yr or $339/2 yrs | Yes, from $108/yr | Yes (Silver+), 1st year included free |
| Battery life | Up to 3 months | Up to 14 days with Power Saving Zones | Up to 14 days + 6mo Reserve Mode |
| Waterproof rating | IP68 and IP66K | IP68 | IP68 |
| Tracks family members too | No | No | Yes, built-in |
| Community lost-pet network | No | No | Yes, 100M+ member network |
| Dedicated pet-only app | Yes | Yes | No, shared family app |
Where Life360 Genuinely Wins
- Your family already uses it. If everyone checks Life360 daily, your dog simply appears on the same map, with no extra app to learn.
- The lost-pet network. Life360 can alert nearby members to help look for a missing pet, something Fi and Tractive do not offer at the same scale.
- Lower upfront cost. At $49.99 with the first year of Silver membership included for new purchases, it is the cheapest way to start.
Where Fi or Tractive Still Make More Sense
- Battery life. Fi is rated for up to 3 months per charge, far longer than Life360 or Tractive.
- Fast live tracking and health data. Tractive’s DOG 6 updates every 3 seconds in Live mode and adds resting heart and respiratory rate.
- Pet-first features. Both are built only for dogs, with activity, sleep and behavior insights instead of a family app with a pet added on.
- Travel. Tractive works in 175+ countries, which suits owners who take their dog abroad.
Our Recommendation
If your family already uses Life360 daily, the Life360 Pet GPS is a genuinely reasonable choice — you’re adding real tracking capability to a habit that already exists, plus getting access to a lost-pet network no dedicated pet tracker can match. If you don’t already use Life360, or you specifically want the longest possible battery life, the Fi Series 3+ remains our top pick for a dedicated, pet-only tracking experience.
Frequently Asked Questions
❓ Can I track my dog and my family on the same app?
Yes, but only with Life360 — Fi and Tractive are dedicated pet-only apps, while Life360 adds your dog to the same family Circle used for tracking people.
❓ Is Life360’s Pet Finder Network actually useful?
It can be genuinely valuable if your dog goes missing, since it can alert a large pool of nearby Life360 members to help search — a scale advantage neither Fi nor Tractive currently offers.
❓ Which has the longest battery life?
Fi leads with up to 3 months per charge, compared to roughly two weeks for both Tractive and the Life360 Pet GPS.
❓ Do I need a Life360 subscription to use the Pet GPS tracker?
Yes — the device requires an active Silver, Gold, or Platinum membership to function, though new purchases typically include the first 12 months of Silver membership at no extra cost.
